#### Bd ft (Bd. ft.)

A board foot is a lumber measurement equal to a board or plank of wood 1 inch thick and 12 inches on each side. The formula for calculating board feet of sawed lumber is

*bd ft = thickness(in) x width(in) x length(ft)/12*. For example, a board that is 1 inch thick, 12 inches wide, and 10 feet long contains 10 board feet of lumber(1x12x10/12=10).

Also known as "Board feet of lumber".
