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.
Lineal, square and board feet. A lineal foot measures one dimensional distance and is expressed as a single number to represent that distance. The length of a 2x4 expressed as 96 illustrates lineal feet. Square foot measures area and is a two dimensional calculation expressed as width x length. The amount of tile needed to cover a 10' x 12' floor will be 120 square feet. Board feet measures volume and is a 3 dimensional calculation. A board foot is a volume of lumber measuring 1 thick x 12 long x 12 wide.
