Question 1

What is the log volume calculation calculator used for?

Accepted Answer

The calculator is used to calculate log volume according to the selected log volume calculation method. It is an important tool for woodworkers in timber records, purchasing, sales and storage.

Question 2

What data must be entered?

Accepted Answer

To calculate the volume, it is necessary to choose a log volume calculation method and enter the log dimensions, especially the diameter and length. In some cases, it is also possible to choose the wood species and whether the measurement is with bark or without bark.

Question 3

Which log volume calculation methods does the calculator support?

Accepted Answer

The calculator supports the main and most widely used log scaling methods and log volume calculation rules from different countries around the world, for example Huber, ČSN 48 0009, STN 48 0009, Sweden, GOST 2708-75, Scribner, Doyle, International 1/4, Smalian (USFS), Newton, Brereton (PNG), Vermont, Universal (Daniels), Ontario Board Foot, Ontario Cubic, Roy, Alberta, BC Firmwood, Hoppus, JAS, Mid-girth, Guo Biao - GB 4814-84 and others.

Question 4

Is the result accurate for every commercial case?

Accepted Answer

The result is approximate and depends on the accuracy of the entered data, the selected method and the way the logs are measured. For commercial or record-keeping use, it is always important to follow the rules applicable to the specific market or standard.

Question 5

What is the difference between the various log volume calculation methods?

Accepted Answer

Different log volume calculation methods use different ways of measuring diameter, length or estimating yield, so the resulting volume may differ from one method to another. Choosing the correct method depends on the country, commercial practice or standard you need to use.

Question 6

Why can the volume differ according to the selected standard or log volume calculation rules?

Accepted Answer

Each method is based on different calculation rules. Some use the mid-diameter, others the small-end diameter, while others use their own tables and coefficients. That is why it is important to choose the method required by the specific market or partner.

Question 7

Does the calculator support international log volume calculation methods?

Accepted Answer

Yes. The calculator supports the main and most widely used log scaling rules and standards from different parts of the world, so it is also suitable for international comparison of calculations.

Question 8

Can I calculate the volume with bark as well as without bark?

Accepted Answer

Yes. For several methods, you can choose calculation with bark or without bark. For measurements with bark, the calculator can also take the wood species into account for an approximate bark volume estimate.

Question 9

Is this calculator suitable for the timber trade as well?

Accepted Answer

Yes. The calculator is suitable for both approximate and practical use in the purchase, sale, record-keeping and checking of log volume. For commercial use, however, it is always necessary to respect the methodology agreed for the specific market or contract.

Question 10

Which method should I choose if I do not know how the volume is measured?

Accepted Answer

It is best to follow the standard or log scaling rule used in your country, company or commercial relationship. If you need a comparison, the calculator allows recalculation according to multiple methods.
