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.
An average weight of a board foot of Douglas-fir, which is not one specific tree but one of about a dozen different trees, is about  2.8 to 2.9 pounds per board foot. You could make a quick calculation based on that. And don't forget that a 2 x 4 is not really 2 by 4 in size.
