The volume (cubature) of raw, unprocessed round timber is determined as follows: measure the diameter (not the radius) at the top end of the log. Measurements are taken in two directions—its maximum and minimum diameters—and then averaged. This average is rounded to the nearest even number. Using the derived figure, the log’s volume in cubic meters is referenced from the standard cubature table without computing any additional averages. By sequentially summing the volume of each log, you obtain the total round timber cubature.
Tired of performing laborious, repetitive calculations when the initial parameters remain constant? Long ago, this challenge was met with the invention of universal cubature tables. These invaluable resources quickly determine the volume of timber, roundwood, processed logs, and beams. However, for newcomers, these extensive tables—filled with an overwhelming array of numbers—can seem perplexing and overly complex.
Our online log volume calculator eliminates the need for cumbersome tables and intricate formulas. One key challenge in computing roundwood volume lies in the varying cross-sectional dimensions of logs. Even if you are well-versed in traditional cubature tables, the repetitive, painstaking calculations can easily lead to mistakes.
There are several methods for manual cubature computation:
Undoubtedly, the most reliable approach is to calculate each log's volume individually. Although this method delivers high accuracy, it is often very time-consuming. Unscrupulous roundwood vendors can take advantage when clients are faced with confusing table values.
The second method assumes that when logs are stacked, they occupy a space that includes interstitial voids. By subtracting 20 percent from the total volume, you obtain an estimated roundwood cubature. However, this approach may lack precision if the logs are arranged unevenly, resulting in larger gaps.
The third method, based on wood density, often yields only an approximate result since the density of similar timber pieces can vary significantly depending on maturity, moisture content, and other natural conditions.
Our program combines calculation precision, speed, and user-friendliness. To compute the volume of unprocessed round timber, simply measure the top-end diameter in two perpendicular directions (minimum and maximum), average the two measurements, and input this value along with the log’s length and quantity. The online calculator processes the remaining steps efficiently. If you also need to calculate the cost of raw timber, just fill in the requisite pricing details, minimizing the potential for errors and fraudulent assessments.
Expressed in cubic meters, our online log volume calculator enables you to quickly and accurately determine timber volume. For example, if you need to compute the cubature of a 6-meter log, simply enter the dimensions into the tool. This helps you avoid mistakes and significantly accelerates the overall process. While traditional cubature tables remain an option, our calculator offers a simpler and more effective alternative.
If you are unsure how to measure a log for cubature computation, just follow these straightforward steps: measure the top-end diameter in two directions, compute the average, and utilize our calculator. The result is an accurate round timber volume calculation in cubic meters, ideal for various construction and design purposes.
