How many milligrams are in 85 grams. So, we will talk about how to correctly calculate the dose of the drug for a child.

Folic acid is one of the vital vitamins. As a rule, there is not so much of it in the usual diet, so vitamin B9 deficiency is far from uncommon. To replenish the balance, you need to know the correct dosage of folic acid and be able to properly use additional folates.

Vitamin B9 (medical name - folic acid) is one of the most important nutrients for humans, which is needed for many processes in the body. Folic acid helps cells grow, maintain the integrity of DNA, so the vitamin prevents the development of cancer.

In addition, folic acid is involved in hematopoiesis, helps the heart and blood vessels. By improving blood circulation, acid has a beneficial effect on the immune system, improves the functioning of the nervous system and the general condition of the body.

BY THE WAY
Our intestines can produce folic acid on its own, but in very small amounts, so the bulk of this vitamin must come from food.

Reception features

Like any other drug, folic acid should be taken regularly. At the same time, consider its interaction with other drugs. For example, acid reduces the effect of phenytoin, therefore, its dose must be increased.

A number of substances reduce the absorption of folic acid by the body:

Antacids
cholestyramine,
some antibiotics (sulfonamides, chloramphenicol, tetracyclines, neomycin, polymyxin)

Reduce the effect of the action can also:

cytotoxic drugs ( Methotrexate),
antibacterial agents (pyrimethamine),
diuretics (Triamterene).

With this option, doctors prescribe calcium folinate instead of folic acid.

How to take for prevention

For prophylaxis, small daily doses of B9 are used: 400 mcg for adult.

Teenagers this dosage may be prescribed for the prevention of anemia, immunodeficiency, and physical retardation.

Women planning a pregnancy, it is recommended to use 1 mg of acid once a day for medicinal purposes for six months in order to reduce all kinds of fetal malformations.

When is the best time to take

"Folk" must be taken orally after meal, as indicated in all instructions for the drug.

The fact is that taking vitamins on an empty stomach can lead to irritation of the gastric mucosa: like other acids, folic acid increases its acidity. This provokes diseases of the stomach - gastritis, ulcers, etc.

If you take a vitamin while eating, food will be more difficult to digest, since the acid forms an insoluble complex with zinc.

Important: if you miss a pill, you do not need to take a double dose

Admission courses

To maintain optimal levels of folic acid in the body, a daily intake is necessary.

ADVICE:
It is better to drink any vitamins in the morning during breakfast, drinking plenty of fluids. So unabsorbed vitamin surpluses can be easily removed by the body

How many folic acid tablets per day should I take

The number of tablets depends on the mass of the active substance in it, since folic acid is now sold in different dosages.

Most often, pharmacies sell folic acid in a dosage of 1 mg. For medicinal purposes, you need to use 1-2 tablets. per day. Pregnant women - 1 tablet per day for prevention.

Folic acid and vitamin E: regimen

Vitamin E and folic acid - a couple of useful elements that complement each other. Most often, gynecologists prescribe this combination of vitamins to girls from the first stages of pregnancy or to those who are just planning it.

Vitamin E and B9 guarantee the full development of the internal organs of the child and the development of the central nervous system. Vitamin E is directly responsible for the reproductive system, increases the fertility of the girl, reduces the threat of miscarriage in the short term, and prevents the placenta from exfoliating.

When used with folic acid, the intestinal wall is strengthened, the mother's condition improves: working capacity increases, immunity increases, the nervous system is restored.

Optimal dosage:

Vitamin B9 (folic acid) - 0.8 mg per day.;
Vitamin E (tocopherol) - 0.3 mg per day..

Is it possible to drink folic acid without a prescription

Any pharmacy will tell you that this medicine is available without a doctor's prescription.

If you find yourself deficient in folic acid, then the smallest daily dose will not harm you, since the excess is excreted by the body on its own.

The best option is dietary supplements, where the composition already contains folic acid. Like vitamin complexes, dietary supplements contain many other useful substances.

ADVICE :
The daily volume of folic acid is determined by various factors: gender, age, lifestyle and body condition; Only a doctor can help you choose.

Despite the widespread belief that folate is easily excreted from the body and its overdose is impossible, it should be borne in mind that the vitamin has a number of contraindications:

hypersensitivity to B9,
malignant anemia,
oncology,
vitamin B12 deficiency.

Release forms

Folic acids in pharmacies can be found in the form of powders or tablets (usually 1 mg, 25 and 50 pieces per pack).

However, there are other forms of release:

100 mcg

the minimum dosage may be prescribed by a doctor for prevention;
100 mcg is how many mg: 0.1 mg

400 mcg

dosage in tablets 400 mcg:
1 tab. per day (if there is no deficiency), or half a tablet (1/2 tablet of acid) at a dosage of 1 mg per day - for children over 4 years old and adults as maintenance treatment; pregnant women to prevent fetal defects
400 mcg is how many mg: 0.4 mg;
folic acid 400 mcg how many tablets:

5 mg is how many grams: 0.005 g

Dosage of folic acid for children

Folic carbon dioxide is necessary for the growth and proper development of the body, because the body's immunity is developed directly in childhood, the main life-supporting systems are formed, so it is important to give the child all the necessary vitamins for its construction.

baby

Infants are recommended 25 micrograms of folic acid each day. With normal development, the baby receives all the nutrients from mother's milk, but if the doctor has identified a lack of nutrients in the newborn, B9 is prescribed additionally. Often, folic acid is required for premature babies.

Teenager

At a transitional age, B9 is necessary for children for the normal course of sexual development: vitamin B9 helps the young body to establish hormonal balance. In adolescence, many face skin problems of the face and body: acne, pimples, redness. With the help of folic acid, you can fight redness and irritation of the skin.

For the prevention of vitamin deficiency, children at this age are recommended to use 150-200 mcg, this is half a tablet with a dosage of 400 mcg. But we must remember that if the body needs to be restored, then the therapeutic dose of acid is determined by the doctor.

schoolboy

Folic acid for school-age children from 6 to 10 years old is prescribed at a dosage of 100 mcg per day; from 10 to 14 years - 150 mcg.

Schoolchildren need vitamin B9 to regulate brain activity in order to help children cope with the study load and relieve emotional stress.

How much folic acid do children need: summarizing

Daily Value for Women

To maintain the balance of vitamins in the body, an adult woman needs to take at least 400 micrograms of folate per day.

In addition to the fact that vitamin B9 strengthens the body, normalizes internal processes and improves the general condition, folic acid (folka, as mothers like to call it) is of particular importance for women:

beneficial effect on the reproductive organs,
stops hair loss, rejuvenates and tones the skin;
normalizes the hormonal background;
reduces the symptoms of menopause;

How many times to take per day

Doctors advise taking folic acid (vitamin B9) like all other vitamins according to the scheme: 1 time per day, preferably in the morning, with meals. Drink a small amount of water.

Daily allowance for pregnancy planning

Pregnant doctors necessarily attribute folates. Normally, a woman should receive 400-600 micrograms of acid per day, this is half a 1 mg tablet.

Daily allowance for pregnant women

How many weeks to take folic acid?

Due to the fact that folates do not accumulate in the body, acid is needed already in the first weeks of pregnancy, doctors recommend taking it even at the planning stage of the baby.

IMPORTANT!A woman's body needs vitamin B9 the most in the first 12 weeks of pregnancy.

Daily allowance for breastfeeding mothers

When breastfeeding, a young mother should drink this medicine with a dosage of at least 500-800 micrograms of "folk" per day. It is better to take it as part of dietary supplements or multivitamins, since not only the mother's body, but also the baby needs nutrients at this moment.

Daily Value for Men

If the male body receives at least 700 micrograms of folic acid daily, then the risk of spermatozoa with different types of abnormalities in the chromosomes is reduced by 25-30%.

To avoid infertility in men, B9 is advised to be taken in conjunction with vitamin E.

When a couple is planning a pregnancy, a man needs to drink folic acid 2-3 months in advance.

Conclusion

Vitamin B9 ( in other words folic acid) participates in the formation of the circulatory system and immunity.
Folic acid is essential women who decided get pregnant, as it participates in the normalization of the process of formation and development of the fetus.
folic acid for men necessary for the good functioning of the digestive tract, improving memory, as well as increasing fertility.
Folic acid is prescribed children to improve appetite, brain function and boost immunity.

When we graduate, we often forget a lot of what we have been through in the program. For example, not everyone remembers how many milligrams are in a gram. However, this knowledge is sometimes simply necessary in everyday life. For example, the correct dosage of various components in cooking, medicine, and cosmetology often depends on how well we have mastered the system for transferring mass from kilograms to grams, from grams to milligrams. Treating this lightly, you can easily spoil the result. After all, it is much easier to figure out how much and where to add, knowing how many milligrams are in a gram. Small values are often used when working with small volumes of substances, and it is very important not to confuse the ratio. Even on the Internet, you can sometimes find statements that confidently say that a gram contains 100 milligrams. But it is quite possible that, after reading such a post, the other person will simply make a mistake with the calculations. So, how many milligrams are there in a gram? And how to do the calculations right?

A milligram is a thousandth of a gram. The meaning of the prefix "milli" means 10 to the -3 power, respectively, indicating one thousandth. That is, one gram consists of one thousand milligrams.

Unit converter

In fact, it is not difficult to translate these quantities even without a calculator. To do this, it is quite enough to use the most elementary knowledge of arithmetic.

In order to make it easier to understand how many milligrams are in 1 gram, I will present an illustrative example:

1 gram is equal to 1000 milligrams

And vice versa:

1 milligram is equal to 0.001 grams

It follows that:

1 kilogram is equal to 1,000 grams, which is equal to 1,000,000 milligrams

With the help of such a simple table, you can correctly calculate the amount of substances.

Knowing how many milligrams are in one gram is necessary if you want to follow the recipes of various cosmetics and medicines correctly. Indeed, situations often arise when we can quite understand all the subtleties and nuances on our own, however, ignorance of how many milligrams are in a gram and well-founded uncertainty about the correctness of the calculations makes it difficult to find a rational solution.

Suppose you need to give medicine to a small child. But it is known that the dosage of some drugs is quite strictly different in adults and babies. In this case, the most difficult thing is to choose the required dose, which will not cause any side effects and negative effects on health, for very young children, up to three years old. Having a whole tablet and knowing its standard weight, as well as the amount of active substance, you can easily do this. In an example, it looks like this.

The weight of the tablet is 500 milligrams. The pediatric dose of this drug is 0.25 grams. Complicated? Not at all. One has only to use the elementary school formula, as everything will fall into place. You can use two different ways to convert values - from grams to milligrams or vice versa. Here is the result:

500 milligrams = 0.5 grams. And you only need 0.25. We divide the tablet into two parts and get the right dose of the necessary medicine.

You can also do the opposite:

0.25 grams = 250 milligrams

The result is two numbers - 500 milligrams and 250 milligrams. And now it is much easier to understand how to properly divide the pill.

I will give a few more examples of converting grams to milligrams and vice versa.

0.12 grams = 120 milligrams.

540 milligrams = 0.54 grams

0.03 grams = 30 milligrams

36 milligrams = 0.036 grams

Here's how you can easily deal with such obscure quantities. There is no need to divide or multiply if you understand the number of zeros correctly. In the 540 milligrams version, 0.54 grams can be obtained by simply moving the separating comma forward three digits, which means three zeros in 1000. Did you remember that there are 1000 milligrams in one gram? And in the case of converting 0.03 grams to milligrams, the comma moves back three digits and the missing zero is added. 0.030 = 30.

How many milligrams in 1 gram: calculation and answer

Sometimes the dose of the active substance is indicated relative to 100 ml or 100 mg. The calculations in this case are similar to the previous ones. How to count if the dose is given per 100 g of liquid? Example: the annotation states that 100 g of the finished solution contains 40 mg of the active substance. We take into account that 100 g is 20 teaspoons of 5 ml. And now we are doing the calculations: the indicated dose of the substance (40 mg) is divided by 20. That is: 40 mg / 20 = 2 mg. Therefore, the dose of the drug in 1 teaspoon of the finished solution is 2 mg

Measures of the volume of liquids

1 teaspoon = 5 ml.

1 dessert spoon = 2 teaspoons = 10 ml.

1 tablespoon = 3 teaspoons = 15 ml.

Composition - 15 mg / 5 ml. (indicated on the package or in the instructions) This means that 1 teaspoon contains 15 mg. medicinal product.

If you are prescribed a single dose of 15 mg, then you should take 1 teaspoon of syrup at a time.

If you are prescribed a single dose of 30 mg, then you should take 2 teaspoons of syrup at a time.

The bottle contains 80 mg / 160 ml, where 80 mg is the active ingredient. In this case, the drug is recommended to take 1 teaspoon 2 times a day.

We calculate the dose in 1 ml: for this, the dose of the substance in the entire volume must be divided by the entire volume of the liquid:

80 mg divided by 160 ml = 0.5 mg in 1 ml.

Since a teaspoon holds 5 ml, we multiply the result by 5. That is: 0.5 mg X 5 \u003d 2.5 mg.

Therefore, 1 teaspoon (single dose) contains 2.5 mg. active substance.

The instructions indicate that 60 ml of the finished solution contains 3000 mg of the active substance.

And 60 ml is 12 teaspoons of 5 ml.

And now we are doing the calculations: the indicated dose of the substance is 3000 mg. divided by 12. That is: 3000 mg / 12 = 250 mg.

So 1 teaspoon of the finished solution is 250 mg.

100 mg. the active substance is contained in 5 ml.

In 1 ml. contains: 100 divided by 5 = 20 mg. active substance.

You need 150 mg.

We divide 150 mg by 20 mg - we get 7.5 ml.

1 ml aqueous solution - 20 drops

STANDARD DILUTION OF ANTIBIOTICS FOR INTRAMUSCULAR ADMINISTRATION

1 mg = 1000 mcg;

1 mcg = 1/1000 mg;

1000 mg = 1 g;

500 mg = 0.5 g;

100 mg = 0.1 g;

1% corresponds to 10 g/l and 10 mg/ml;

2% 20 g/l or 20 mg/ml;

1:1000 = 1 g/1000 ml = 1 mg/ml;

1:10,000 = 1 g/10,000 ml = 0.1 mg/ml or 100 µg/ml;

1:1,000,000 = 1 g/1,000,000 ml = 1 µg/ml

If the solvent is not provided in the package, then when diluting the antibiotic by 0.1 g (100,000 IU) of the powder, take 0.5 ml. solution.

So for breeding:

0.2 g. 1 ml is needed. solvent;

0.5 g. You need 2.5-3 ml. solvent;

1 g needs 5 ml. solvent;

In the vial of ampicillin is 0.5 g of dry drug. How much solvent should be taken to make 0.5 ml. the solution was 0.1 g of dry matter.

When diluting the antibiotic for 0.1 g of dry powder, take 0.5 ml. solvent, therefore:

0.1 g of dry matter - 0.5 ml. solvent

0.5 g of dry matter - X ml. solvent

Answer: to 0.5 ml. the solution was 0.1 g of dry matter, 2.5 ml should be taken. solvent.

In a vial of penicillin is 1,000,000 IU of a dry drug. How much solvent should be taken to make 0.5 ml. solution was 100,000 units of dry matter.

100,000 units of dry matter - 0.5 ml. dry matter

1 000 000 IU - X ml. solvent

Answer: so that in 0.5 ml of the solution there are 100,000 units. dry matter, you need to take 5 ml. solvent.

In the vial of oxacillin is 0.25 g of dry drug. How much solvent do you need to take in order to 1 ml. the solution was 0.1 g of dry matter.

1 ml solution - 0.1 g.

X ml. - 0.25 g.

Answer: so that in 1 ml. the solution was 0.1 g of dry matter, 2.5 ml should be taken. solvent.

The patient needs to enter 400,000 IU. penicillin. A bottle of 1,000,000 units. Dilute 1:1.

How many ml. solution must be taken.

When diluted 1:1 in 1 ml. solution contains 100,000 IU. 1 bottle of penicillin 1,000,000 IU. dilute 10 ml. solution.

If the patient needs to enter 400,000 units, then 4 ml must be taken. the resulting solution.

Attention! Before using medications, you should consult your doctor. The information is provided for informational purposes only.

Often, five to ten years after graduation from school, the acquired knowledge fades somewhat in our memory. Most often this is due to the fact that we do not need to use them in real life. However, if the dates of birth of writers, complex chemical formulas and other specific knowledge are really hardly useful to us in everyday life, it makes sense to refresh some of the information obtained during your stay at the school bench. So, for example, do you remember how many milligrams are in a gram?

We ask about this not out of idle curiosity. Cooking, medicine, and cosmetology often work with small doses of substances. In this case, the result of the efforts expended directly depends on whether you are able to correctly translate one value into another: whether it will be possible to treat guests with delicious pastries, correctly calculate the dosage of medicine for a child, surprise friends with home-made cosmetics. Therefore, knowledge of how many milligrams in a gram in everyday life is necessary.

Gram as a unit of mass

Let's start with what a gram is as a unit of mass. For the first time, the idea that the system of measures needed to be somehow unified was thought about in France back in the 17th century, but work on the theory of a unified metric system began in earnest only in 1790. The National Assembly instructed the Academy of Sciences of the French capital to prepare a new system of measures. In 1795, an unchanging unit of length was established - the meter, which is one forty-millionth part of the Paris meridian. After that, the scientists Antoine-Laurent de Lavoisier and Rene-Just Gahuy presented their own developments for determining the weight of water, which were to form the basis of a gravity measurement system. The very idea of using water to determine the unit of measurement of mass belongs to the British philosopher John Wilkins, who first voiced it back in 1668.

So, the concept of a gram was introduced - the weight of one cubic centimeter of pure water at the temperature of ice melting. The official "date of birth" of the gram is April 7, 1795. The Greek word "γράμμα" (gramma) means "little weight".

Since in those days trade dealt mainly with objects whose weight was many times greater than one gram, it became necessary to determine some more significant standard of mass. As a result, it was decided to introduce the concept of a kilogram - the equivalent of the mass of one cubic decimeter of water.

In 1889, during the First International Conference of Weights and Measures, the kilogram standard was introduced - you must admit that it is not very convenient to use water to determine the mass. As a result, a cylinder was made from an alloy of platinum and iridium, which is still stored in the Chamber of Weights and Measures to this day. Copies of it are also available in other countries.

So how many milligrams in a gram?

If everything is more or less clear with grams and kilograms, then the question of how many milligrams are in one gram can confuse some people. Moreover, there are people who are absolutely convinced that a milligram is a hundredth of a gram. However, this opinion is erroneous.

The prefix "milli-" means a thousandth. In other words, there are a thousand milligrams in one gram. Thus, a milligram is one thousandth (0.001) of a gram.

Sometimes it may be necessary to convert milligrams not only to grams, but also to kilograms.

100 mg how many grams the table is complete. How many milligrams in a gram and why you need to know.

To do this, remember that there are a thousand grams in one kilogram. Taking into account the fact that there are 1000 mg in 1 gram, it can be calculated that there are 1,000,000 milligrams in one kilogram: (1000 mg * 1000 g).

Now let's try to use the acquired knowledge in practice. Sometimes young mothers publish panic messages on thematic forums: the drug is recommended for a child in a dose of 0.25 g, and the tablet weight is 500 mg. Does this mean that you should immediately run to the pharmacy and look for a medicine in a different dosage - or can you use a simple formula and convert one unit to another?

500 mg is 0.5 g (0.001 * 500).

Therefore, a dose of 0.25 g can be obtained by dividing the tablet in half.

Here are a few more multiple units of measurement:

1 mg = 0.001 g;
1 mg = 1000 mcg;
1 mg \u003d 1 * 10-8 centners;
1 mg = 1 * 10-9 tons.

More about kilogram

Kilogram(in Russian designation: kg; in international: kg) is a unit of mass.

How many milligrams in a gram and why you need to know

It is one of several (seven) main units of measurement included in the international system of measures.

In 1901, the real concept of the kilogram was stated by the 3rd General Conference on Weights and Measures as follows: the kilogram is a unit of mass, which is equal to the mass of the international sample of the kilogram. The most important sample (standard) of a kilogram is located in the International Bureau of Weights and Measures, located in the city of Sevres near Paris. This is a cylinder with a height and diameter of about 39.17 millimeters made of a platinum-iridium alloy. It is 10% iridium and 90% platinum.

At first, the kilogram was defined as the mass of one liter (cubic decimeter) of absolutely pure water at atmospheric pressure at sea level and at its temperature of 4 ° C. By coincidence of historical circumstances, the term "kilogram" already includes the decimal prefix "kilo", because of this, multiple and submultiple units are created by combining the designations of the unit of measurement "gram" or standard SI prepositions to the name. It is in the international system of measures is fractional: 1 gram = 10-3 kg.

Duplicate sample 1 kg, located in the United States of America (USA).

At the current time, the kilogram is a unique unit of the international system of measures, defined with the help of an object made by mankind - a platinum-iridium sample. With the help of the basic (fundamental) physical laws and properties, all other units of measurement are now determined. The measure "kilogram" was established as the mass of 1 cubic decimeter of water at 4°C when the metric system was introduced in the 18th century. At this temperature, water has the highest density. In 1799, a platinum weight was made, which was used as a sample of a kilogram, but its mass was 0.028 grams more than the mass of 1 cubic decimeter of water. - iridium alloy.

After those times, he is under three sealed caps in the International Bureau of Weights and Measures. As national samples of the kilogram, specially made exact official copies of the international standard are used. In total, over 80 duplicates were created. Two duplicates of the international standard were transferred to Russia, they are stored in the All-Russian Research Institute of Metrology named after Mendeleev. About once every ten years, all national duplicates are compared with international ones.

Comparisons indicate that the accuracy of national samples is approximately 2 micrograms. There is no reason to believe that the international standard is more accurate, since they are in the same conditions. For various reasons, the international sample loses 3 10-8 of its mass in 100 years. At the same time, based on the concept, the mass of the international standard is exactly equal to one kilogram. That is why all changes in the real mass of the sample change the unit of measurement "kilogram". In its Resolution in 1999, the Twenty-first General Conference on Weights and Measures, precisely because of the effort to correct the inaccuracies previously indicated, invited national laboratories to continue their efforts to improve the clarification of the relationship of basic or atomic constants with units of mass, assuming a future definition of the kilogram. In the next decade, a number of international organizations worked to create conjectural options for redefining the kilogram.

The basic unit of mass is gram and its derivatives - milligram and microgram.

Common abbreviations:

gram - g;
milligram - mg;
microgram - mcg.

In 1 g - 1,000 mg or 1,000,000 mcg.
In 1 mg - 1,000 mcg.

1.0 is a gram;
0.001 is a milligram;
0.000001 is a microgram.

The basic unit of measurement for volume is milliliter . A liter habitual in everyday life as a dose is rarely used, but still it is sometimes used. For example, "the volume of fluid required for a cleansing enema is 1 liter" or "the daily volume of infusion therapy is 1.5 liters."

Common abbreviations:

liter - l;
milliliter - ml.

In 1 liter - 1000 ml.

The unit of volume must be specified!

If it is not indicated, that is, 15.0 is simply written, it means that this is not a volume, but a mass - 15 grams. If we are talking about milliliters, then next to the number 15 it should be written - ml: 15.0 ml.

Please pay attention: the most common parenting mistake is when they get confused MG and ML.

Once again, we pay attention, because this particular moment is extremely relevant!

Do not confuse units of mass and units of volume - this is very, very important!

Whenever a drug is prescribed parenterally in a certain amount of ml, we are talking about the fact that this volume will be measured with a syringe for injection of the appropriate size or an infusion solution bottle with appropriate volume marks will be used.

Packages of modern medicines dispensed in milliliters for reception inside without fail contain special measuring devices: caps, pipettes, syringes, cups, measuring spoons.

If there is nothing like this, but the medicine is still prescribed inside and in ml, which means that injection syringes or special graduated measuring cups sold in pharmacies should be used to measure the required volume.

A non-standard and inaccurate unit of volume is a drop . The volume of a drop is largely determined by the physical properties of the dispensed liquid.

For example, the volume of one drop alcohol solution is on average 0.02 ml, and the volume of one drop water solution can range from 0.03 to 0.05 ml.

Pharmacists and doctors have long agreed that the standard pharmaceutical, medical measure of a drop is 0.05 ml.

Thus, 1 ml = 20 drops.

When a solution of a particular drug is prescribed to your child in drops and we are talking about a modern drug, the package usually contains a special pipette or the bottle cap is a special dropper.

If there is no pipette or dropper cap, then you can use a standard medical pipette sold at any pharmacy. If many drops are prescribed, it is quite possible to use a disposable syringe to measure the required volume of fluid.

Assigned to 10 drops - so it's 0.5 ml; 40 drops - respectively, 2 ml.

You can even use the formula:

number of ml = number of drops divided by 20.

The main thing to remember is that whenever a certain drug is prescribed in drops, and you cannot figure out how to extract and measure these drops, so, in such situations, it is clearly understood that the volume of one drop is 0.05 ml. And this means that, having a medical syringe with a volume of 1 ml in the house, you can easily and absolutely accurately determine the required amount of medicine: 2 drops - 0.1 ml, 3 drops - 0.15 ml, 5 drops - 0.25 ml etc.

Even more non-standard (compared to drops) units of volume are various household spoons, which are sometimes (but less and less often) used to dose inactive and relatively safe drugs.

Standard volume of spoons in ml:

tea room spoon - 5 ml;
dessert spoon - approximately 10 ml (there is no single standard);
dining room spoon - in the CIS countries - 18 ml, in the USA, Canada - 15 ml, in Australia - 20 ml;

In some countries, the concept of a baby spoon is used.

children's spoon - 10 ml.

To completely close the topic of kitchen utensils for measuring volume, recall glass . Dosing with glasses is more common in cooking, but is sometimes used in medicine to measure the volume of infusions, decoctions, rinses, etc.

one glass - 200 ml.

The active substance is present in a liquid medicinal product at a certain concentration. The digital value of this concentration is reflected in such a seemingly obvious, but not always clear expression, as solution percentage .

The expression "5% solution of ascorbic acid" does not look complicated and mysterious at all. But still, some explanations should be given in order to finally dot the i's.

So, the concentration in pharmacology is usually displayed as number of units of mass per unit volume. Thus, the expression "1% solution" means that 100 ml of liquid contains 1 g of the active substance.

In the vast majority of cases, the amount of fluid prescribed to a child is measured in milliliters. Therefore, we recalculate:
100 ml - 1 g;
10 ml - 0.1 g;
1 ml - 0.01 g.
0.01 g is 10 mg. Quite a logical conclusion: in 1 ml of 1% solution contains 10 mg of active ingredient .

We train:

in 1 ml of a 5% solution of ascorbic acid - 50 mg of ascorbic acid;
in 1 ml of a 50% solution of analgin - 500 mg of analgin;
in 1 ml of a 0.1% solution of loratadine - 1 mg of loratadine;
in 1 ml of 66.7% solution of lactulose - 667 mg of lactulose;
in 1 ml of a 0.05% solution of chlorhexidine - 0.5 mg of chlorhexidine ...

Manufacturers of children's dosage forms are very skeptical about parental mathematical abilities. The instructions may well say “loratadine solution 0.1%”, but the package will indicate in capital letters: “loratadine 1 mg / 1 ml” or “loratadine 5 mg / 5 ml”.

A huge number of liquid medicines are available in different concentrations. In 1 ml of a suspension of paracetamol there may be 20, or maybe 50 mg: “120 mg / 5 ml” or “250 mg / 5 ml” will be written on the box with the suspension. The pharmacy worker will not be able to release correctly, and the mother will not be able to correctly give the child paracetamol prescribed at a dose of “5 ml of suspension” - you need to know what concentration of the suspension is in question. Thus, Whenever your child is prescribed anything liquid, it is important to make sure that you know not only the name of the solution, but also its strength!

The situation when a doctor prescribes a solution, syrup, suspension, etc., but does not indicate the concentration, is nevertheless possible.

So, for example, lactulose syrups are produced by almost all manufacturers in the form of a 66.7% solution. And when the doctor wrote: Lactulose syrup 5 ml in the morning before breakfast”, then there is no error in this.

Another option: we are talking about a drug prescribed under a specific trade name.

An example of such an assignment: nurofen for children, suspension, at temperatures above 39 ° C 10 ml orally". Suspension called "Nurofen for children" is available in only one concentration - 100 mg / 5 ml. Therefore, everything is written correctly, it is impossible to make a mistake.

Another question is that in a pharmacy they can tell you something like this: “We do not currently have Nurofen for children in suspension. We have another medicine, but in the composition of ibuprofen, as in Nurofen, and this is different - only in tablets of 0.4. Everything else is in the regional center, the bus tomorrow morning ... "

And then you calculate:

10 ml with a concentration of 100 mg / 5 ml - this means we were prescribed 200 mg.

And in a tablet 0.4 is 400 mg.

So, we will persuade Mashenka to swallow half a tablet ...

Another fundamentally important point. Knowing the concentration is necessary not only when drugs are taken orally and are dosed in ml. For topical application and dosing with drops, this is no less important.

And if assigned xylometazoline 2 eachdrops in each nostril 3times a day”, then before dripping, you should definitely clarify which xylometazoline we are talking about - 0.1% or 0.05%?

The concentration of the active substance in dermatological products is also indicated by percentages, but there is no specificity here. So if it says " hydrocortisone ointment 1% ”, This means that 1 ml of this ointment contains 10 mg of hydrocortisone. But just like with a suspension of paracetamol, you can’t just write “hydrocortisone ointment”, since this ointment comes in 0.5%, 1%, 2.5% ...

Now about dosing using special units . Always, when it comes to certain dosage units, the number of these units is linked either to a unit of volume, or to a specific package or dosage form. And this relationship must be clarified without fail!

That is, you must definitely know that in 1 ml of solution insulin contains exactly 40 units or exactly 100 units of the drug.

You need to know exactly what is in this tablet with pancreatin contains a dose equal to 10,000 units of lipase. Exactly 10 thousand, not 40 or 25.

You must know that it is in this sterile vial that there are 500,000 units of sodium salt benzylpenicillin.

Once again, I would like to emphasize that always, when something is prescribed in units, it is imperative to clarify in what volume, in which vial, in which capsule exactly this number of units is contained.

The use of the name of a particular dosage form as a dosing unit is associated with enormous difficulties and many errors.

In one tablet of the same pharmaceutical agent, there may be a different amount of active ingredient. So, for example, in one tablet paracetamol may be 80, 120, 125, 200, 285, 325, 500 or 564 mg. Obviously, no one will be able to properly sell in a pharmacy or give a child paracetamol prescribed in a dose of "1 tablet".

Therefore, next to the name of the drug and the selected dosage form, the amount of the active substance in this particular dosage form prescribed for a particular patient should be indicated.

Examples:

calcium gluconate, tablets of 0.5;
cephalexin, capsules of 0.25.

An indication of a certain tablet or capsule, in the absence of information about the content of the active substance, can in some cases be justified by the fact that there is no choice of tablets of this particular drug.

This is possible if:

the drug is produced in this dosage form only with a strictly defined amount of active substance. For example, ornidazole Available in tablets of 0.5. There are no other pills. Make no mistake;
the drug is prescribed under a trade name, and a specific manufacturer produces it only in such a dosage form - there is no choice. For example, one tablet suprastin always contains 0.025 chloropyramine. Therefore, if suprastin is prescribed one tablet twice a day, you will not be mistaken;
a drug is a strictly defined combination of certain ingredients protected by a trade name. For example, decathylene, lozenges. There is no other decathylene. You won't be mistaken.

We already know that the optimal way of dosing drugs to children is based on the relationship of the dose with the weight of the child.

Consider the intricacies of such dosing using the example of the most popular children's antipyretic - paracetamol.

From paragraph 2.1. we know that single dose paracetamol is 10-15 mg/kg.

We have a child weighing 15 kg. Thus, a single dose of the drug is from 150 (10 x 15) to 225 (15 x 15) mg.

We bought a 120 mg/5 ml suspension. This means that in one ml - 24 mg. And we need from 150 to 225. So, our single dose is approximately equal to 6.2-9.3 ml.

We bought a 250 mg/5 ml suspension. This means that in one ml - 50 mg. And we need from 150 to 225. So, our single dose is 3-4.5 ml.

We bought 200mg tablets. And we need from 150 to 225. So, our single dose is 1 tablet.

We bought 325mg tablets. And we need from 150 to 225. So our single dose is half a tablet.

Now let's deal with daily dose the same paracetamol. If there are indications, this medicine can be given repeatedly during the day, but not more than 4-5 times, and it is very important that the interval between doses be at least 4 hours.

All the same child - body weight 15 kg. The maximum daily dose of the drug should in no case exceed 60 mg / kg. This means that our baby can take no more than 15 x 60 - 900 mg per day.

We bought a 120 mg/5 ml suspension. This means that in one ml - 24 mg. And we need no more than 900. So, our maximum daily dose is 37.5 ml (900/24).

We bought a 250 mg/5 ml suspension. This means that in one ml - 50 mg. And we need a maximum of 900 per day. This means that our daily dose should not exceed 18 ml (900/50).

We bought 200mg tablets. So, no more than four tablets per day.

We bought 325mg tablets. So our maximum daily dose is 2 tablets and another three-quarters of a tablet.

Already this enumeration shows that, knowing the weight and the required single / daily dose, it is quite easy to make a rational choice of dosage form. It is obvious that in most cases it is much easier to give a child 3 ml of suspension than 10 ml or half a tablet. Therefore, for a child weighing 15 kg, the optimal dosage form of paracetamol will probably be a suspension of 250/5 ml.

Even more indicative in this aspect is the choice of the optimal dose of paracetamol for rectal administration.

It is known that when using suppositories, a single dose of paracetamol is higher than when taken orally, and is 20-25 mg / kg. Thus, a child weighing 10 kg should receive a suppository containing 200 to 250 mg. We go to the pharmacy, and there it turns out that paracetamol suppositories are on sale, containing the active substance in an amount of 50, 80, 100, 125, 150, 250, 300, 500, 600 and even 1,000 mg. In our situation, it is most logical to buy candles of 250 mg and use them with a minimum load for the child's psyche. But you can not know all this and mock the child by putting two 100 mg candles into it, or mock yourself by trying to cut off half of the 500 mg candle.

We also draw your attention to the fact that a careful study of the sheet with medical prescriptions in many cases will allow you to save significant funds.

Assignment example: " azithromycin suspension. 200 mg 1 once a day half an hour before meals, 3 consecutive days". We go to the pharmacy, and there it turns out that the antibiotic azithromycin in suspension is sold in the following packages:

powder for suspension 100 mg/5 ml, bottle 20 ml;
powder for suspension 200 mg/5 ml, 15 ml vial;
powder for suspension 200 mg/5 ml, 30 ml vial;
powder for suspension 200 mg/5 ml, bottle 20 ml.

It is clear that the optimal choice in our situation is 200 mg / 5 ml, a 15 ml bottle - this is just enough for the prescribed course of treatment. Any other packaging is not economically viable: either you have to buy more, or it remains.

Unfortunately, there is often a situation where the doctor simply does not have time to follow the rapidly changing assortment of pharmacies. And in this case, such appointments are quite possible: loratadine 5 mg 1once a day for 2weeks". This, of course, is wrong, but a very slight parental intellectual effort can solve the problem.

So let's go to the pharmacy. - We need loratadine, 5 mg.

It turns out that loratadine is available in tablets of 10 mg, as well as in syrups or suspensions - 1 mg / 1 ml.

5 mg is half a tablet or 5 ml of syrup. We don’t want to share pills, and our baby has problems swallowing pills, so we get liquid-tasty and give what the doctor ordered ...

By the way, before buying, we carry out simple calculations: 5 ml per day, yes for 2 weeks, this is 5 x 14 - it turns out that 70 ml is needed for a course of treatment. How much is in the bottle? We are interested: it turns out that in one bottle of syrup or suspension of loratadine there can be 30, 50, 60, 100, 120 and 150 ml. It is probably the most rational to buy a bottle of 100 ml - please give ...

And the last thing I would like to draw your attention to. Whenever a doctor prescribes to divide tablets, this is either indicated by the words (half, third, quarter), or by a fraction: 1/2, 1/3, 1/4.

And if it says "calcium gluconate 0.5" - this is not half a tablet (!), It's half a gram - 0.5 g.

0.25 is not a quarter of a tablet, it is 0.25 g.

Here and below, when we say "basic unit", we mean the unit, basic in terms of drug dosing. That is, we know that from the point of view of the international system of units (International System, SI), the basic unit of mass is the kilogram (kg), and the standard unit of volume is the cubic meter (m 3).

In ordinary life, we very often have to deal with the measurement of weight, whether it is our own weight or a purchased product. However, most often it is kilograms and grams. And in very rare cases - milligrams. Despite the seeming simplicity of the question, not every person will be able to immediately remember how many milligrams are in a gram. Although very often his life depends on the correct answer to this question.

What unit of measure is the gram

Before remembering how many milligrams are in a gram, it is worth brushing up on the knowledge of a gram. So, the gram is a unit of the SI system, designed to determine the mass. Its homeland is France, hence the melodic name gramme. The gram as a unit of measurement was introduced in the last decade of the eighteenth century.

By weight, it is equal to 0.001 kilograms, (0.000001 tons, 0.00001 centners) in other words, there are a thousand grams in one kilogram.

Gram is denoted by the letter "g" in Cyrillic and the letter g in Latin.

Like other SI units, grams are used to measure weight in science, technology and in everyday life in most countries of Europe and the world. However, in the United States and some other countries, in the old fashioned way, weight is measured in pounds (pound), it is equal to approximately 0.45 kilograms. As in the old days, some countries have their own numerical equivalent of the pound, which is why there is confusion when converting to SI. In connection with this situation, countries using pounds are gradually starting to switch to kilograms.

An interesting fact, Russia also had its own pound, and it was a little heavier than the modern one.

In the system of measuring weight in pounds, there is also a kind of analogue of a gram - an ounce (oz). It is equal in weight to 28.4 grams.

How many milligrams in one gram

Kilograms, centners and tons are units of measurement that are larger than a gram. But there are those that are smaller than it, the so-called "submultiple units". These include: milligram (mg-mg), microgram (mcg-mkg), nanogram (ng-ng) and pictogram (pg-pg). In addition to the milligram, all the rest are rarely used in everyday life, since there is no special need, and to measure them, you need an ultra-sensitive scale, which is not cheap.

The answer to the question of how many milligrams are in 1 gram is the number 1000, that is, one gram consists of a thousand milligrams, or 0.001 grams in one milligram.

Why do you need to know how many milligrams are in a gram

A milligram is a tiny measure of weight, which at first glance seems unsuitable for measuring anything with it in everyday life. After all, no one will measure sugar or cereals in milligrams.

However, if a person feels unwell and needs medication, starts calculating the required dosage of the drug, he will immediately understand why it is important to know how many milligrams are in a gram. After all, many drugs are prescribed in relation to the weight of the patient. And if a sick child or teenager, then the dose of the medicine should be small, most often less than a gram, so you need to clearly understand the gram / milligram ratio, otherwise you can cause irreparable harm to health.

For example, on vacation the child was bitten by a bee, the bitten place was swollen, which means that it is necessary to take an antihistamine. However, in the first-aid kit, this medicine is available only in tablets. After reading the instructions carefully, you can understand that one tablet weighs 1 gram, but children weighing up to 10 kilograms can be given no more than 250 milligrams of the drug at a time. With knowledge of a milligram, you can easily calculate the allowable dose: 1 g \u003d 1000 mg, 1000/250 \u003d 4, it turns out that only a quarter of a tablet can be given to a child at a time.

In recent years, it has become fashionable to prepare cosmetic skin care products with your own hands.
Especially popular was the manufacture of so-called soap from scratch. Despite the simplicity of the process, it is important to follow the dosage exactly, otherwise you can get burned. After all, if it is incorrect to calculate the proportion of oils and caustic soda, then either not all of the soda will interact with the oils and the rest of it will get on the skin when using soap; or there will be too much oil and the soap will not clean well.

milligram and milliliter

When analyzing the topic of milligrams, one cannot but mention the milliliter (ml). They are very often confused. It is worth remembering that milligrams measure weight, and milliliters measure volume. So the liquid is measured only in milliliters, and the scale for dividing syringes is milliliter, not milligram. Tablets and powders are always measured in milligrams.

These two measures are equal in some cases, in other situations it is necessary to know the density of the liquid being measured in order to accurately calculate its weight.

Almost every day when shopping in a store, people have to convert kilograms to grams and vice versa, so this skill has been brought to automatism. In the case of grams and milligrams, this is all done in a similar way. Therefore, having learned how many milligrams are in a gram, you can then, if necessary, carry out these calculations yourself.

The school ended a long time ago and the basic knowledge is somewhat shaken. Not so much, of course, as to completely forget the metric values, but you can’t immediately answer how many mg in 1 gram.

Restoring memory

From arithmetic we know that 1 g is a multiple of 1 kg, that is, a thousandth of a kilogram. And when you need to find out how many grams are in a kilogram, we multiply the figure denoting kilograms by a thousand and get:

1 kg x 1000 \u003d 1000 g, or 1 kg \u003d 10 3 g.

So, a milligram is also a thousandth of a value, which is called a gram.

And similarly, the problem is solved when you need to find out how many milligrams are in it.

We attribute three zeros to the number that indicates the amount of g.

1 g x 1000=1000 mg, or 1 g=10 3 mg. Here is such a simple answer to the question - how many mg are in 1 gram.

Putting knowledge into practice

Life constantly confronts us with a situation where we have to solve such arithmetic problems. Most often, this occurs when taking medications.

For example, if the instructions for use say that more than 0.2 g of the drug should not be consumed per day, and the weight of 25 mg is indicated on the tablets in the blister, then you need to find out how many tablets you can use.

Solution algorithm: 0.2 g x1000 = 200 mg, 200 mg: 25 mg = 8 tablets.

But the reverse conversion from milligrams to grams is also common, especially when cooking or for chemical solutions in household

We remember that if 1 g = 10 3 mg, then 1 mg = 10 -3 g or 1 mg = 0.001 g.

Suppose, according to the recipe, we need to add 300 mg of granulated sugar and 800 mg of salt somewhere, and our scales measure only g.

Let's translate the required values into the desired unit of measurement.

300:1000=0.3 g or 300 x 0.001=0.3 g

800:1000=0.8 g or 800 x 0.001=0.8 g

Thus, relying on mnemonics, i.e. taking as a basis an analogue of a kilogram and a gram, it is possible to strengthen in memory the conversion of grams to milligrams.

And here is some more interesting information in the table below:

In contact with

Instruction

To convert grams to milligrams, multiply the number of grams by a thousand. That is, use the following simple formula:
Kmg \u003d Kg * 1000, where
Kmg - the number of milligrams,

Kg is the number of grams.
So, for example, the mass of one tablet of activated carbon is 0.25 grams. Therefore, its mass, expressed in milligrams, will be: 0.25 * 1000 \u003d 250 (mg).

If the number of grams is an integer, then to convert grams to milligrams, simply add three zeros to the right of it.
For example, one tablet of ascorbic acid with glucose weighs 1 gram. So, its mass in milligrams will be: 1,000.

If the number of grams is expressed as a decimal fraction, then move the decimal point three digits to the right.
For example, the glucose content in one tablet of ascorbic acid with glucose is 0.887 grams. Therefore, in milligrams, the mass of glucose will be 887 mg.

If there are less than three digits after the decimal point, pad the missing characters with zeros.

So, for example, the content of ascorbic acid in one tablet of ascorbic acid with glucose is 0.1 grams. In milligrams, this will be - 100 mg (according to the rule, it turns out 0100 mg, but the leading zeros on the left are discarded)..

If all initial data are given in grams, and the result must be presented in milligrams, then carry out all intermediate calculations in grams, and translate milligrams only as a result of calculations.
So, for example, one tablet of allochol contains:

Dry bile - 0.08 g,

Dried garlic - 0.04 g,

Nettle leaves - 0.005 g,

Activated carbon - 0.025 g.

To calculate: how many milligrams of active substances are contained in one tablet of allochol, add up the masses of all components, expressed in grams, and translate the result into milligrams:

0.08+0.04+0.005+0.025=0.15 (d).

0.15*1000=150 (mg).

Gram is a unit of mass measurement belonging to the system of metric measures. Gram is one of the basic units of the CGS system of absolute measures (centimeter, gram, second) - widely used before the adoption of the international measurement system (SI). Referred to as g or g. Multiple unit of mass kilogram is one of the basic SI units, denoted by kg or kg.

Home " Medicines » 0 3 g how much will be in milligrams. How many milligrams in a gram and why you need to know.

Measures of the volume of liquids

1 teaspoon = 5 ml.

1 dessert spoon = 2 teaspoons = 10 ml.

1 tablespoon = 3 teaspoons = 15 ml.

Example: 1

Composition - 15 mg / 5 ml. (indicated on the package or in the instructions) This means that 1 teaspoon contains 15 mg. medicinal product.

If you are prescribed a single dose of 15 mg, then you should take 1 teaspoon of syrup at a time.

If you are prescribed a single dose of 30 mg, then you should take 2 teaspoons of syrup at a time.

Example: 2

The bottle contains 80 mg / 160 ml, where 80 mg is the active ingredient. In this case, the drug is recommended to take 1 teaspoon 2 times a day.

We calculate the dose in 1 ml: for this, the dose of the substance in the entire volume must be divided by the entire volume of the liquid:

80 mg divided by 160 ml = 0.5 mg in 1 ml.

Since a teaspoon holds 5 ml, we multiply the result by 5. That is: 0.5 mg X 5 \u003d 2.5 mg.

Therefore, 1 teaspoon (single dose) contains 2.5 mg. active substance.

Example: 3

The instructions indicate that 60 ml of the finished solution contains 3000 mg of the active substance.

And 60 ml is 12 teaspoons of 5 ml.

And now we are doing the calculations: the indicated dose of the substance is 3000 mg. divided by 12. That is: 3000 mg / 12 = 250 mg.

So 1 teaspoon of the finished solution is 250 mg.

Example: 4

100 mg. the active substance is contained in 5 ml.

In 1 ml. contains: 100 divided by 5 = 20 mg. active substance.

You need 150 mg.

We divide 150 mg by 20 mg - we get 7.5 ml.

DROPS

1 ml aqueous solution - 20 drops

1 ml alcohol solution - 40 drops

1 ml alcohol-ether solution - 60 drops

STANDARD DILUTION OF ANTIBIOTICS FOR INTRAMUSCULAR ADMINISTRATION

1 mg = 1000 mcg;

1 mcg = 1/1000 mg;

1000 mg = 1 g;

500 mg = 0.5 g;

100 mg = 0.1 g;

1% corresponds to 10 g/l and 10 mg/ml;

2% 20 g/l or 20 mg/ml;

1:1000 = 1 g/1000 ml = 1 mg/ml;

1:10,000 = 1 g/10,000 ml = 0.1 mg/ml or 100 µg/ml;

1:1,000,000 = 1 g/1,000,000 ml = 1 µg/ml

If the solvent is not provided in the package, then when diluting the antibiotic by 0.1 g (100,000 IU) of the powder, take 0.5 ml. solution.

So for breeding:

0.2 g. 1 ml is needed. solvent;

0.5 g. You need 2.5-3 ml. solvent;

1 g needs 5 ml. solvent;

Example: 1

The vial contains 0.5 g of dry drug. How much solvent should be taken to make 0.5 ml. the solution was 0.1 g of dry matter.

When diluting the antibiotic for 0.1 g of dry powder, take 0.5 ml. solvent, therefore:

0.1 g of dry matter - 0.5 ml. solvent

0.5 g of dry matter - X ml. solvent

Answer: to 0.5 ml. the solution was 0.1 g of dry matter, 2.5 ml should be taken. solvent.

Example: 2

The vial contains 1,000,000 units of dry medicine. How much solvent should be taken to make 0.5 ml. solution was 100,000 units of dry matter.

100,000 units of dry matter - 0.5 ml. dry matter

1 000 000 IU - X ml. solvent

Answer: so that in 0.5 ml of the solution there are 100,000 units. dry matter, you need to take 5 ml. solvent.

Example: 3

The vial contains 0.25 g of dry drug. How much solvent do you need to take in order to 1 ml. the solution was 0.1 g of dry matter.

1 ml solution - 0.1 g.

X ml. - 0.25 g.

Answer: so that in 1 ml. the solution was 0.1 g of dry matter, 2.5 ml should be taken. solvent.

Example: 4

The patient needs to enter 400,000 IU. penicillin. A bottle of 1,000,000 units. Dilute 1:1.

How many ml. solution must be taken.

When diluted 1:1 in 1 ml. solution contains 100,000 IU. 1 bottle of penicillin 1,000,000 IU. dilute 10 ml. solution.

If the patient needs to enter 400,000 units, then 4 ml must be taken. the resulting solution.

Brief information about the units of measurement "International unit"

International unit (IU)- in pharmacology, it is a unit of measurement of the amount of a substance, based on biological activity. Used for vitamins, hormones, certain drugs, vaccines, blood constituents and similar biologically active substances. Despite the name, the IU is not part of the international SI measurement system.

The exact definition of one IU varies for different substances and is established by international agreement. The Committee for Biological Standards at the World Health Organization provides reference blanks for certain substances, (arbitrarily) sets the number of IUs they contain, and defines biological procedures for comparing other blanks with reference blanks. The aim of such procedures is that different preforms having the same biological activity contain an equal number of IUs.

For some substances, over time, mass equivalents of one IU were established, and measurement in these units was officially abandoned. However, the IU unit may still remain in wide use due to convenience. For example, vitamin E exists in eight different forms that differ in their biological activity. Instead of specifying the exact type and weight of the vitamin in the preparation, it is sometimes convenient to simply indicate its amount in IU.
Wikipedia

International unit (IU)— internationally agreed standards needed to compare the levels of different biological compounds tested on the basis of their potency.
