To find board
footage from linear footage, multiply the decimal factor times
the linear footage.
To find linear
footage from board footage, divide the board footage by the decimal
factor.
If you do
not have a factor, multiply the size of the piece times the linear
footage and divide by 12.
Example:
You have 120 LF of 5x5 and you don’t know the 5x5 factor.
5x5x120LF
12 =
250 Bd. Ft.
