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 ...
{{convert|123|cuyd|m3+board feet}} → 123 cubic yards (94 m 3; 40,000 board feet) The following converts a pressure to four output units. The precision is 1 (1 decimal place), and units are abbreviated and linked.
Flute size refers to the number of flutes per linear foot, although the actual flute dimensions for different corrugator manufacturers may vary slightly. Measuring the number of flutes per linear foot is a more reliable method of identifying flute size than measuring board thickness, which can vary due to manufacturing conditions.
100 fbm [convert: unknown unit] does not work either. Peter Horn User talk 23:41, 30 December 2020 (UTC) I'm not sure that this should "work". Nominally a "board foot" is 1" x 1' x 1', so 1/12 cu ft, and this volume could be converted to cubic metres, but it would not represent any actual property of the wood involved, so could be just misleading.
Also rendered board-foot and abbreviated as BDFT or BF. A unit of volume of lumber , defined as the volume of a board or plank of wood that is one foot long, one foot wide, and one inch thick, i.e. 12 in × 12 in × 1 in (305 mm × 305 mm × 25.4 mm), which is equivalent to 1 ⁄ 12 of a cubic foot (ft 3 ), 144 in 3 , or 2,360 cm 3 .
The attenuation coefficient of a volume, denoted μ, is defined as [6] =, where Φ e is the radiant flux;; z is the path length of the beam.; Note that for an attenuation coefficient which does not vary with z, this equation is solved along a line from =0 to as:
The name of the unit is required. The plural name is optional. If no plural name is given, it is created by appending "s" to the singular name. For example, the ft unit has name "foot" and plural name "feet"—the plural name is necessary to avoid the plural of "foot" being "foots". The US name is optional.
