Board Foot BD/FT. The basic unit of measure for lumber cut from a log is the board foot. A board foot contains 144 cubic inches of volume. It is generally easiest to compare any piece of lumber to a board foot of lumber measuring one (1) inch thick, twelve (12) inches wide and onne (1) foot long. Lumber under one (1) inch thick is generally considered the same as one (1) in thick for estimating purposes. Chances are that you will never need to order lumber by the board foot unless you buy in large quantities, but its interesting to know that lumber is generally sold by the thousand board foot and prices are converted for the consumer.
Square Foot SQ/FT The second unit of measure would be the square foot which would be a piece of lumber measuring 12 inches by 12 inches. It would not necessary be one (1) inch thick, it could be 2 or 3 inches. Flooring, for instance, could be sold by the square foot.
Linear Foot LN/FT The third unit of measure would be the linear foot. That would be a piece of lumber twelve (12) inches long. It could be 8 LN/FT of 2x4 or 8 LN/FT of molding. |
