Some methods are based on mathematical formulas ( JAS; Doyle to name two) and others use fixed values for certain diameters that come from tables ( GOST ). A very important part of the log volume calculation is rounding the diameter.
What is the best way to calculate the content of timber?
For cases where timber has been stacked with both the ends mixed, we suggest using the Cylindrical (also known as “True content of cylinder”) formula, which is also available in Timbeter. This is the dominant method used in most of continental Europe.
What is the best way to measure logs?
The Cylindrical Formula is the most straightforward and used formula for fast measurements. It doesn’t mean that the method is the most accurate and should not be used to calculate all kinds of logs, due to their unique structures and timber being a highly valued and prized commodity.
What is the best way to measure Roundwood?
Cylindrical formula is mostly used to measure pulp-and fuelwood and is the conventional method used in Central-Europe. The Japanese Agricultural Standard Scale was developed for measuring roundwood in the late 1940s and became popular in Eastern Asia, Oceania (including Australia) and Chile.
How do you find the volume of a round log?
The cubic feet, or volume, of a cylindrical log is given by the volume of a cylinder V=πhr2. A log with radius of 2 feet and height of 10 feet would have a volume of about 125.66 cubic feet (or ft3).
How do you calculate the volume of a piece of wood?
The volume of wood is the length of the pole times the cross-sectional area. A circle (the cross-section) has an area equal to π times the square of the radius. The radius is the circumference divided by 2π. Thus your volume of wood in cubic feet is 20 × 52 ÷ (4π).
How do you calculate cubic meters of a log?
Apply the formula for volume of a cylinder, V = π × r2 × h, where V is the log's volume, r is the radius of the log and h is its height (or if you prefer, its length; the straight-line distance from one end of the log to the other).
How are timber logs measured?
The board foot is the most common standard used for saw logs and lumber. A board foot contains 144 cubic inches of sawed lumber or the equivalent of a board 1 inch thick, 12 inches wide and 1 foot long. A second unit of measure is the cord.
What is the the formula for volume?
Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height. How you refer to the different dimensions does not change the calculation: you may, for example, use 'depth' instead of 'height'.
