The board-foot is a specialized unit of volume for measuring lumber in the United States and Canada. It is the amount of wood in a 12-inch long 1-inch-by-12-inch board (or 1 foot × 1 inch × 1 foot, about 30 × 2½ × 30 cm³), or the equivalent (144 cubic inches, 2.36 litres). Unfortunately, it is not truly a measure of volume, due to nominal and actual measures used in the lumber business. In addition, the definition is different for hardwood and softwood. en.wikipedia.org/wiki/Board_feet
