The board-foot is a specialized unit of measure for the volume of lumber in the United States and Canada. It is the volume of a one-foot length of a board one foot wide and one inch thick.
Board-foot can be abbreviated FBM (for "foot, board measure"), BDFT, or BF. Thousand board-feet can be abbreviated as MFBM, MBFT, or MBF. Similarly, million board-feet can be abbreviated as MMFBM, MMBFT, or MMBF.

The English last could also be understood as the volume occupied by the other lasts. In some sources, the last is equated with 640 gallons. The beer last was 12 barrels, the cod last and some herring lasts were also 12 barrels, and the pitch last was 12 or 14 barrels.
