Board foot. A board foot (BF) is the unit of measurement for hardwood lumber. A board foot is 1 foot long x 1 foot wide x 1 inch thick. (1 foot = 0.305 metres, 1 inch = 25.4mm) The formula for determining board feet in a board is: (Width in inches x length in feet x thickness in inches) divided by 12. The percentages of clear wood required for each grade are based on this 12' unit of measure.
If you are a landowner planning to sell logs to a lumber mill, you need to have a good idea of the logs' value. Lumber mills pay according to the number of board feet, or board footage, in the logs. One board foot is equal to the amount of wood in a one-inch-thick board that measures 1-foot by 1-foot. Board footage is calculated based on a log's diameter and length. You should check with your local sawmill to find out specific guidelines for determining board feet before you enter into a final contract.
