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 .
But besides those older (traditional and normal) situations, in recent years some product lines have been widened to also market boards in standard stock sizes; these usually retail in big-box stores and using only a relatively small set of specified lengths; [c] in all cases hardwoods are sold to the consumer by the board-foot (144 cubic ...
Dimensional lumber sizes such as "2 by 4" refers to a board whose finished dimensions are closer to 1 + 1 ⁄ 2 inches by 3 + 1 ⁄ 2 inches (1 + 3 ⁄ 4 inches by 3 + 3 ⁄ 4 inches is typical in the United Kingdom).
The product is manufactured as a 12-by-12-inch (300 mm × 300 mm) or 12-by-18-inch (300 mm × 460 mm) billet in a rectangular cross-section, which is then typically sawn and trimmed to smaller cross-sectional sizes.
A cord of wood. The cord is a unit of measure of dry volume used to measure firewood and pulpwood in the United States and Canada.. A cord is the amount of wood that, when "racked and well stowed" (arranged so pieces are aligned, parallel, touching, and compact), occupies a volume of 128 cubic feet (3.62 m 3). [1]
The density of the board, when evaluated in relation to the density of the fibre that goes into making the panel, is important. A thick MDF panel at a density of 700–720 kg/m 3 (44–45 lb/cu ft) may be considered as high density in the case of softwood fibre panels, whereas a panel of the same density made of hardwood fibres is not regarded ...
A0 has a surface area of 1 square metre (11 sq ft) up to a rounding error, with a width of 841 millimetres (33.1 in) and height of 1,189 millimetres (46.8 in), so an actual area of 0.999949 square metres (10.76336 sq ft); A4 is recommended as standard paper size for business, administrative and government correspondence; and A6 for postcards ...
There is little evidence that the dimensions of these early racks were standardized. Telephone equipment racks (1923) The 19-inch rack format with rack-units of 1.75 inches (44.45 mm) was established as a standard by AT&T around 1922 in order to reduce the space required for repeater and termination equipment in a telephone company central office .
