Why use our calculator?

Timber has been an indispensable building and finishing material throughout human history because of its affordability, durability, natural beauty and, of no small importance in recent times, environmental friendliness.

Almost all of the assortment of lumber on the market is dispensed per unit volume and much less per area. In order to estimate how much wood I need to order for a project requires much calculations.

The universal lumber calculator from KALK.PRO allows you to convert lumber from pcs to cubes and back from cubes to pcs. The tool works only with rectangular and radial assortments, and also provides the ability to know the total weight of materials and cost per unit for clarity. The result can be saved for free in PDF format.

How much timber I need? Step by step

Determine the type of calculation:

Select the first option if you need to calculate how many pieces in a cube (for example, how many in 1 m³);
Select the second option if you need to calculate how much volume the selected lumber has;

Select the cross section of the lumber: rectangular, round;
Specify the dimensions: width, thickness, diameter, and length of the product;
Specify the number of cubes or the number of pieces;
Choose a type of wood (pine by default);
Enter cost per cubic.
