Cord (unit)

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 m3). This corresponds to a well-stacked woodpile 4 feet (122 cm) high, 8 feet (244 cm) wide, and 4 feet (122 cm) deep; or any other arrangement of linear measurements that yields the same volume.

The name cord probably comes from the use of a cord or string to measure it.

The face cord is a unit of volume for stacked firewood, 4 feet (122 cm) high, 8 feet (244 cm) wide, and 16 inches (41 cm) deep—equal to 1/3 of a cord. The symbol for the unit is fc - cd.
