How to calculate how much timber in 1 cube?

We offer a simple calculation so that you do not get lost with the question of how to find out how much timber is in a cube. These calculation options are suitable if you know the dimensions of the timber. For example, let's take a bar 260 x 260 x 6,000 mm (6 meters). The same can be done for a beam measuring 3 meters, 4 meters, 5 meters.

The formula for calculating the volume of a beam:
100mm 100mm 6000mm = 0.1m 0.1m 6m = 0.06m3

The formula for calculating the beam in pieces:
Bar length - 6 meters
1m 3 / 0.06m 3 \u003d 16 pcs / m 3

Complicated? It seems to be no! But if the calculation causes you difficulties, just use our table. The table contains a calculation for all known sizes of timber, which are given in GOST 8486-86.

How to calculate how much timber in 1 cube

Why do you need to know how much timber is in 1 cube?

There are two reasons for this:

You can immediately calculate the total price of the volume of timber you need. To do this, you need to know the volume of 1 piece of timber, the price for 1 cube and how many pieces will be needed to implement your plans.
You can calculate the total number of timber units needed to complete the project. And you can do this by knowing how many cubes are required for work, and by calculating the number of pieces of timber in 1 cube.

When starting to build or repair a wooden house, you have to purchase various boards, while the buyer knows the total length, but the seller sells lumber by volume. This article will help you correctly determine the number of any boards in one cubic meter, which will help you avoid buying too much lumber.

How to calculate the volume of edged boards

Determining the volume of one board is done in the same way that was used in school - by multiplying the length by the width and thickness. Or by multiplying the width by the length and thickness. It doesn't matter in which order you multiply the dimensions of the board, the result will always be the same. For example, a standard fifty-fifty board has the following dimensions:

length 6 meters;
width 20 centimeters;
thickness 5 centimeters.

To facilitate multiplication, it is necessary to convert all dimensions to common units - meters or centimeters. It is easier to carry out these calculations in meters, then you do not have to divide the resulting number by a million in order to convert to cubic meters.

As a result of multiplication, we obtain the volume of one board of 0.06 cubic meters.
After that, we divide the unit by 0.06 and get the number of boards in one cubic meter.
We get the number 16.6666, which must be rounded to the nearest integer, that is, up to 16, which will be the number of "fifty" boards in one cubic meter. It is always necessary to round down, because some of the boards may turn out to be a little wider or thicker, they may not be tightly stacked, or several boards from the package will turn out to be twisted. If all the boards turn out to be normal, then fractions can also be taken into account, this is especially true for a thick beam.

Table of standard volume values

For your convenience, we have created a table with the most common sizes of boards and timber, as well as their number in one cubic meter.

What is a cubic meter of edged board

How many edged boards in one cube - Photo

Edged board- lumber with cleanly cut edges, without bark residues. The width of the edged board exceeds the thickness at least twice.

Since the fee is charged for the volume in cubic meters, we recall the geometric formula for its definition:

W * H * D = volume.

Everything is in meters.

To find out how many boards are in one cube:

1 / (W * H * D) = number of boards in 1m3 (cube)

where, W- Width, AT- Height, D- Length

Translation: 1mm=0.001m, 10mm=0.01m, 100mm=0.1m

Below is a table of some types of edged boards and their volume

When buying lumber in small quantities, you can get confused with decimal places, namely with rounding. An experienced seller will round the resulting number to the 3rd decimal place. The experienced buyer will round up GOST y - up to 0.000001 cubic meters and remind the seller that up to 0.001 cubic meters. meters are rounded only a batch of boards. The most common quantity - from several boards to 2-4 cubic meters - does not make up a batch. In order not to offend either one or the other, they are rounded to 4 decimal places.

Then the resulting volume is multiplied by the cost of 1 m3 (cube). And here the number of decimal places can significantly affect costs.

1 edged board 32 mm thick, 200 mm wide and 6 m long(32X200X6000) has volume

0.032 * 0.2 * 6 = 0.0384 cubes

30 boards will have volume

0.0384 * 30 = 1.152 cubes

If the seller rounds the volume of 1 board to 0.04 cubic meters, he will additionally receive income:

0.04 * 30 \u003d 1.2 cubes
1.2 - 1.152 = 0.048 cubes

Selling these 0.048 "air" cubes makes the buyer's wallet easier

The cost may vary depending on the type of wood. Grading decreases with a decrease in quality: the presence of wood defects and deviations from standard sizes. If the floorboard has a curvature, narrower or thinner than the standard by 3-5 mm, it will not work completely. Visual inspection of the lumber is just as important as accurate sizing.

Edged board area covered

To find out how much lumber you need, the calculation of the board in a cube will help you. The above formula is based on the definition of area

W * D = area.

Having calculated the covered area, it remains to multiply it by the desired thickness of the board

W * D * 0.022; 0.025; 0.032; 0.04m and so on.

It remains to see how many boards are in one cube, and determine the required number. Just in case, print or memorize the table above.

You also need to take into account the future cutting of the material.The floorboard and sheathing board "lining" have an overlapping tongue, which is taken into account in the cubature, but is not included in the area to be covered. A couple of boards are needed have in reserve .

Determining the volume of unedged boards

How many unedged boards are in one cubic meter - Photo

Unedged board, that is, not having a rectangular section along the entire length, is much cheaper and is widely used for the installation of various kinds of rough battens, temporary fences.

It is important to understand that the top and bottom of such a board must be sawn along the entire length. If one face is not propylene, then this is already croaker. The definition of the cubic capacity of such lumber differs precisely in that it does not have the correct geometric shape.

The current standards establish several ways to account for unedged material, and it is almost impossible to calculate exactly how many boards are in 1 cube.

Batch.
Piece by piece.
Sampling method.

In batch In this case, the boards are tightly packed into a bag of the correct shape with further measurement. Further calculation is carried out according to the standard formula for determining the volume. using various coefficients.

Piece measurement made according to average measurements of height and width. The largest and smallest dimensions in meters are added and divided in half.

(Wmax + Wmin) / 2 * (Hmax + Hmin) / 2 * L = volume, m3

where, W- Width, AT- Height, D- Length

If it is visually visible that the wood is fresh and, accordingly, damp (humidity above 20%), then the seller is obliged to reduce the total volume by multiplying the received cubic capacity by the coefficient:

0,96 for softwood
0,95 for deciduous.

Sampling method used to determine the volume of a large batch of unedged lumber. When loading, for example, into the body of a vehicle, every fifth, tenth or twentieth board is measured using the second method.

The resulting volume is multiplied by five, ten, twenty. Loading continues to the next control board. The selection of control boards in a separate foot is also practiced. The calculation is made after the loading is completed.

Calculating the volume of a bar: how much is a bar in a cube?

Calculation of the amount of timber in one cube - Photo

The beam differs from the edged board only in that all its faces or two opposite ones have the same size: more than 0.05 m in thickness and 0.013 m in width. The formula for determining its volume is standard

R beam size	The volume of one bar	Bar in 1m3 (cube)
100×100×6000	0.06 m³	16 pcs.
100×150×6000	0.09 m³	11 pcs.
150×150×6000	0.135 m³	7 pcs.
100×180×6000	0.108 m³	9 pcs.
150×180×6000	0.162 m³	6 pcs.
180×180×6000	0.1944 m³	5 pieces.
100×200×6000	0.12 m³	8 pcs.
150×200×6000	0.18 m³	5.5 pcs.
180×200×6000	0.216 m³	4.5 pcs.
200×200×6000	0.24 m³	4 things.
250×200×6000	0.3 m³	3 pcs.

W * T * D = volume of timber, m3.

To find out how much timber is in one cube

1 / (W * T * D) = amount of timber in 1 m3 (cube)

where, W- Width, T- thickness, D- Length

Translation: 1mm=0.001m, 10mm=0.01m, 100mm=0.1m

When buying a beam, the volume must be determined by the piece, since the beam is laid with spacers in the stack. The measurements of such a stack and the calculation of the cubature according to the above formula invariably lead to a significant overestimation of the volume.

Length of 1 cube of timber (and any edged lumber) in meters is determined by dividing the unit by thickness and width. For example, you need to find out how much timber is in one cube - a face of 180 mm.

1 / (0.18 * 0.18) = 30 meters 87 cm.

1 meter of such a beam will have the following volume.

0.18 * 0.18 * 1 = 0.0324 m3.

These calculations may be needed when determining the cost of funds and material.

Construction log volume: how many logs are in one cube?

How many logs in one cube: calculation - Photo

Log buildings are and will be relevant. The determination of the volume of round material depends on the method of its production.

Construction log of manual debarking.
Construction log, rounded on special machines.

The section of the barrel for trimming by hand has the shape of a slightly truncated cone, so the cylinder volume formula is used, but with some peculiarities.

3.14 * r 2 * L = log volume, m3

Here
r- average radius, calculated as (r 1 + r 2) / 2, r 1 - radius from one end of the log, r 2 - radius from the other end of the log.
L- log length.
3,14 - constant "Pi".

The rounded log has, of course, a cylindrical shape and is calculated according to the above formula. But here the radius is measured at any end once. Determining the number of logs in 1 cube is determined similarly to a beam.

1 / (3.14*r2 * L) = Number of logs in 1m3 (cube)

Blanks for construction logs are measured in the same way.

The radius (diameter divided in half) is measured without taking into account the thickness of the tree bark. In practice, manual calculations are not carried out. They use special tables summarized in a cubature book. They are also available in electronic form.

In conclusion, it should be noted that lumber for critical work, standard in size, wood species and humidity, should be purchased at large sites. A small producer, as a rule, is not allowed there due to the lack of appropriate control over the quality of their products.

In preparation for the construction of a frame house, the construction of a roof and the assembly of log crowns, the developer has to deal with the purchase of timber.
This material is used for the manufacture of various wooden structures, so its assortment includes dozens of items. To eliminate errors, you need to determine as accurately as possible how much timber is in a cubic meter.

The "mathematical model" of this operation is simple. To calculate the volume of any rectangular object, its length is multiplied by its width and height. However, in practice, when buying a large number of timber of different lengths and sections, you can get confused and overpay a considerable amount.

In this article, we will talk about the important nuances of calculating the volume of sawlogs and give easy-to-use cheat sheets for converting linear meters of timber into cubes.

Be careful at the timber warehouse!

Given the high cost of edged timber, its purchase must be treated responsibly. Sellers, as a rule, use the price per 1 m3. When calculating the roof truss system, wall frame, floor beams and floor, customers receive linear meters. Additional confusion is introduced by production length standards, which range from 3 to 6 meters (0.5 meter increments).

It is not difficult to put everything “on the shelves” in this matter. Let's say that for construction you need a bar with a section of 100x50 mm, and its total length is 100 running meters (p / m). To calculate the volume of edged wood, you need to convert the cross-sectional area from millimeters to square meters and then multiply them by the length: 0.1x0.05x100 \u003d 0.50 m3. We get the price of a given amount of timber by multiplying its volume by the cost of one cubic meter.

And here is another equally important question: how to control the amount of sawlogs that the seller releases to you? Here it is necessary to take into account not only the cross section, but also the length of the material.

Let's say that we need a beam 4 meters long (total length 100 p / m). In this case, the volume of one piece will be equal to: 0.1x0.05x4 = 0.02 m3. Dividing the purchased amount of material (0.5 m3) by the volume of one bar (0.02 m3) we get exactly 25 pieces.

In practice, round numbers are rare, so the required amount of timber most often turns out to be fractional. We will not give the seller that part of the lumber that remains after the decimal point. Better pay him up to a whole number of bars.

Consider an example. 63 linear meters of timber are purchased (section 100x180 mm, length 6 meters). We consider the purchase volume: 63x0.1x0.18 = 1.134 m3. We divide it by the volume of one bar (0.1x0.18x6 m / n \u003d 0.108 m3). We get 1.134 / 0.108 = 10.5 pieces. The seller will not cut half the timber for us. Therefore, when calculating, you need to pay him up to a whole amount and pick up 11 bars.

With a profiled beam, the cross section of which has a complex shape, they proceed in the same way as with a regular one. To determine the cross-sectional area of a given material, its total height (the distance from the bottom edge with the groove to the top mark of the spike) is multiplied by the width.

Considering the amount of timber in 1m3 in the warehouse, take a tape measure and measure the actual cross section of the purchased material. It may turn out that instead of the 100x200 or 150x150 mm promised by the seller, he was delivered thinner material. Even 1 centimeter reduction in the transverse dimension of the sawlog results in significant losses for the buyer.

Another important nuance is the technological deviation of the length of the timber. It can reach 5-7 centimeters, since the ends of the logs are not cut off during processing. Remember that the seller does not have the right to add these extra centimeters to the total length.

Tables for quick calculation of the volume of timber

It is not always convenient to count on a calculator how many pieces of timber in a cube, especially when buying a large batch. The seller's data can be easily controlled using ready-made tables. Here, for standard sizes of sawlogs, information is given on the volume of 1 beam and the number of pieces in 1m3.

Table for counting edged timber 6 meters long

Dimensions (mm)	Volume of 1 piece (m3)	Pieces per 1 m3
100x100x6000	0,06	16
100x150x6000	0,09	11
100x180x6000	0,108	9
100x200x6000	0,12	8
150x150x6000	0,135	7
150x180x6000	0,162	6
150x200x6000	0,18	5,5
180x180x6000	0,1944	5
180x200x6000	0,216	4,5
200x200x6000	0,24	4
250x200x6000	0,3	3

This table can also be used when buying a 3-meter beam. To do this, the volume of 1 piece must be halved, and the amount of material in one cube multiplied by 2.

Recall that, by definition, lumber is considered to be lumber with a thickness and width of 100 mm or more. Therefore, we deliberately did not include the dimensions of wooden blanks of a smaller section in the table in order to maintain formal accuracy.

Let's look at the data on the volume and number of boards of running sizes in a separate table:

Dimensions (mm)	Volume of 1 piece (m3)	Pieces per 1 m3
25x100x6000	0,015	66,6
25x150x6000	0,0225	44,4
25x200x6000	0,03	33,3
40x100x6000	0,024	41,6
40x150x6000	0,036	27,7
40x200x6000	0,048	20,8
50x50x6000	0,015	66,6
50x100x6000	0,03	33,3
50x150x6000	0,045	22,2
50x200x6000	0,06	16,6
50x250x6000	0,075	13,3

To calculate the volume and quantity of a 4-meter beam, you can use the following cheat sheet:

Dimensions (mm)	Volume of 1 piece (m3)	Pieces per 1 m3
100x100x4000	0,04	25
100x150x4000	0,06	16,66
100x180x4000	0,072	13,88
100x200x4000	0,08	12,5
150x150x4000	0,09	11,11
150x180x4000	0,108	9,26
150x200x4000	0,12	8,33
180x180x4000	0,13	7,69
180x200x4000	0,144	6,94
200x200x4000	0,16	6,25
250x200x4000	0,2	5

As can be seen from the table, almost the entire range of bars here turns out to be fractional. Therefore, for an economical purchase, you should use our advice on paying the seller up to the whole amount of timber.

How to do it practically? Let's take an example. Let's say that we bought one cubic meter of a 4-meter beam with a section of 100x180 mm (according to the table, 13.88 pieces are obtained). The price of 1m3 is 6500 rubles. Up to 14 pieces of bars, we need to pay extra 14-13.88 = 0.12. The volume of this "piece" is (0.12 x 4 meters = 0.48 m) x 0.1 x 0.18 m = 0.00864 m3. We multiply it by the price of 1 m3 and get 0.00864 m3 x 6500 rubles. = 56.15 rubles.

Remember that the purchased volume of bars must include a margin (loss during cutting during operation). Therefore, the result obtained in the process of theoretical calculation of the roof truss system or other wooden structure must be multiplied by a factor of 1.3. After this adjustment, you can start settlements with the seller.

In addition to determining the volume and price of the purchased material, you need to know the weight of 1 m3 of timber in order to order transport of the appropriate carrying capacity.

The weight of a cubic meter of timber depends on the type of wood and its moisture content. The approximate weight of 1 m3 of dry pine is 510 kg (raw - 890 kg).

The average weight of one cube of dry spruce bars is 450 kg (raw - 790 kg).

The weight of dried oak wood is in the range from 700 to 800 kg/m3, and wet (freshly cut) - from 980 to 1030 kg/m3.

Dry larch timber weighs 650 kg/m3. Freshly sawn material of this type of wood weighs 840 kg/m3.

It would seem, why do you need to know how many boards are in one cubic meter? After all, with a large construction, boards are sold anyway in “m 3” and payment is made precisely for the volume, and if only a few pieces are needed, then the cost is determined by linear meters. And yet, it is necessary to understand how such a calculation of the material is made.

With the proper organization of work, the first stage is always such an item as planning. And not only the design and features of the future structure, but also material costs. Therefore, if in accordance with the project 40 boards are required, then, given the marriage or inaccuracy, you will have to buy - with a margin - 45 pieces. For this, you should calculate how many “cubes” you need to purchase and add a few more blanks to them.

Why?

First of all, the number of boards in 1 m 3 depends on their parameters (thickness, length, width). Naturally, for each size their number in the "cube" will be different.

Secondly, when carrying out any work, whether it is a new building or renovation, different boards are always used. For the rafter system - one, for the floors - others.

Thirdly, buying extra material is a waste of money. Of course, the boards will come in handy later, but they need to be stored somewhere. And not just leave it on the site, and then get "rotten", but provide the proper conditions. And given that we have never had a shortage of wood, is it worth buying much more than necessary?

Fourth, time factor. And if there are not enough boards when purchasing in cubic meters? What, stop work, look for trucks, waste time going to points of sale?

And fifth, you should not hope that the Seller will answer such a question. At best, he will offer to count the boards in piles himself, if interested. At worst, on purpose or out of ignorance, he will deceive.

We offer you a table with ready-made data:

It has only 3 columns. The first shows the dimensions of the blanks (in "mm"), the second - their number in 1 m3, and the third - the volume of 1 board (also in "m3"). There is nothing complicated. It is only necessary to find the corresponding line, and the answer to the question of interest has been received.

By the way, it's very convenient. If we multiply the entire required number of boards by the volume of one, it will become clear how many "cubes" will have to be purchased, which means how much money will have to be spent. This is exactly what a good owner should do. And tables are not needed, just use a calculator.

This table provides data for both edged and unedged boards. In addition, there are calculations for, which is also often used in construction or repair.

In principle, this is quite enough.

Note

All of the above is true if the edged board is purchased. But it also costs more. It is more cost-effective to take raw material if it is possible to trim it yourself. But in this case, it is necessary to apply a coefficient when calculating. Experts believe that 20-30 percent of unedged lumber will go to waste. Therefore, from 1 "cube" of finished boards, you will get less.
