Here in the states we have several different scales to determine how many board feet are estimated to be in a log. Each method of scaling has a different conversion factor to convert to cubic meters. The different conversion factors are to simply make up the differences in the estimated board feet, determined by the different
scaling methods. If you can determine the board
feet, or other method of determining how much
wood is in the log, you should be able to
convert it to cubic meters, as it is simply a method to determine volume.
