how much lumber can you get from your trees?
"Board feet" is a unit of measurement for lumber, equal to one square foot of wood that is one inch thick. "Log board feet" is a measure of the amount of usable lumber that can be obtained from a log, calculated by multiplying the log's diameter and length by a "scaling factor" that takes into account the log's taper and defects. Log board feet can be used to estimate the value of a tree or a group of trees before they are harvested.
Our Calculations are using the Doyle Rule for measuring board-feet
The Doyle rule for measuring log board feet is a method used to determine the volume of a log in board feet. It is based on the formula:
Board Footage (Doyle)=((D−4)/4)²×L
Let's use the Doyle Log Rule formula to calculate the estimated board footage for a log with a diameter () of 10 inches and a length () of 17 feet:
Plugging in the values:
Board Footage (Doyle)=((10−4)/4)²×17
Board Footage (Doyle)=(6/4)²×17
Board Footage (Doyle)=(3/2)²×17
Board Footage (Doyle)=(9/4)×17
Board Footage (Doyle)=153/4
Board Footage (Doyle)=38.25
So, according to the Doyle Log Rule, the estimated board footage for the given log is approximately 38.25 board feet.
While the Doyle Rule is not 100% accurate, it is the commonly accepted method of measuring board-foot.
