Log rules used to measure the volume of a log with the result in board feet. One board foot measures 12 inches x 12 inches x 1 inch and in theory, one cubic foot contains 12 board feet. But this does not usually apply to a board foot scaling rule as this does not take into account the amount of waste of cutting a log into usable sections that can be measured in board feet. The one and only exception to this is the Brereton log rule that converts one cubic foot to 12 board feet.
