- A board foot is a wood measurement for a piece of lumber 12 inches wide by 1 ft long by 1 in thick or 12 in wide by 12 in long by 1 in thick.
- Board foot can be abbreviated as FBM (for "foot, board measure"), BDFT, or BF.
- 1 board foot is also the same as 144 cubic inches.
- In simple terms this is a volume of a rectangular wood divided by 12, thus it would be (length)(width)(thickness)/12.
Where the unit of the length must be in ft and the thickess and width must be in inches.
12 inches = 1 ft
1 inch = 2.54 cm =254 mm = 0.254 m
1 yard = 3 feet
