What is Board Feet mean?
The board foot or board-foot is a unit of measurement for the volume of lumber in the United States and Canada. It equals the volume of a one-foot (305 mm) length of a board, one foot wide and one inch (25.4 mm) thick.
Board foot can be abbreviated as FBM (for "foot, board measure"), BDFT, or BF. A thousand board feet can be abbreviated as MFBM, MBFT, or MBF. Similarly, a million board feet can be abbreviated as MMFBM, MMBFT, or MMBF.
Until 1970s in Australia and New Zealand the terms super foot and superficial foot were used with the same meaning.

An example of planed lumber is softwood 2 × 4 lumber sold by large lumber retailers. The 2 × 4 is actually only 1+1⁄2 in × 3+1⁄2 in (38 mm × 89 mm), but the dimensions for the lumber when purchased wholesale could still be represented as full 2 × 4 lumber, although the "standard" can vary between vendors. This means that nominal lumber includes air space around the physical board when calculating board feet in some situations, while the true measurement of "board feet" should be limited to the actual dimensions of the board.
For planed lumber, board feet refer to the nominal thickness and width of lumber, calculated in principle on its size before drying and planing. Here the actual length is used.
See dimensional lumber for a full discussion of the relationship of actual and nominal dimensions. Briefly, for softwoods, to convert nominal to actual, subtract 1⁄4 inch (6 mm) for dimensions under 2 inches; subtract 1⁄2 inch (13 mm) for dimensions over 2 inches and under 8 inches; and subtract 3⁄4 inch (19 mm) for larger measurements. The system is more complicated for hardwoods.
