​Board foot (bd. ft.)

The board-foot is a specialized unit of measure for the volume of lumber in the United States and Canada. It is the volume of a one-foot length of a board one foot wide and one inch thick.

Board-foot can be abbreviated FBM (for "foot, board measure"), BDFT, or BF. Thousand board-feet can be abbreviated as MFBM, MBFT or MBF.

Cubic meter (m3)

SI derived unit of volume. It is the volume of a cube with edges one metre in length. An alternative name, which allowed a different usage with metric prefixes, was the stère. Another alternative name, not widely used any more, is the kilolitre.

NHLA Grading

NHLA grades are based on the percentage of clear-defect free wood on a board. The measurements of this percentage are referred to as clear-cuttings. Other than the FAS grades, the grade of the board is determined from the percentage of these clear cutting and do not consider defects outside the clear areas.
