# 1217.4 Board foot.

*Board foot* or *BF* means a unit of measurement of softwood lumber represented by a board 12-inches long, 12-inches wide, and 1-inch thick or its cubic equivalent. A board foot calculation for softwood lumber 1 inch or more in thickness is based on its nominal thickness and width and the actual length. Softwood lumber with a nominal thickness of less than 1 inch is calculated as 1 inch.
