The board foot or board-foot is a unit of measurement for the volume of lumber in the United States and Canada [1]. It equals the volume of a board that is one foot (30.5 cm) in length, one foot in width, and one inch (2.54 cm) in thickness, or exactly 2.359 737 216 liters. Board foot can be abbreviated as FBM (for "foot, board measure"), BDFT ...
A board foot is a United States and Canadian unit of approximate volume, used for lumber. It is equivalent to 1 inch × 1 foot × 1 foot (144 cu in or 2,360 cm 3). It is also found in the unit of density pounds per board foot. In Australia and New Zealand the terms super foot or superficial foot were formerly used for this unit. The exact ...
In 1950, the United States produced 38 billion board feet of lumber, and that number remained fairly constant throughout the decades moving forward, with the national production at 32.9 billion board feet in 1960 and 34.7 billion board feet in 1970. [61]
IOW, the "board foot" is not really a unit of volume, it is a way of describing timber by referring to fictional dimensions of the tree the timber came from. Unless there is a corresponding system of nominal volume in the metric system, it is misleading to add "conversions" to lots of sizes in FBM or whatever.
As previously noted, less wood is needed to produce a given finished size than when standards called for the green lumber to be the full nominal dimension. However, even the dimensions for finished lumber of a given nominal size have changed over time. In 1910, a typical finished 1-inch (25 mm) board was 13 ⁄ 16 in (21 mm). In 1928, that was ...
