cord [cd] Unit Converter

Definition of cord [cd] unit

A cord is a traditional unit of volume for measuring stacked firewood, equal to 128 cubic feet (about 3.62 cubic metres). It represents a neatly stacked pile typically measuring 8 feet long, 4 feet high, and 4 feet deep.

History of cord [cd] unit

The cord developed in North America as a practical way to measure firewood before standardized commercial systems became common. The name probably refers to the cord or rope once used to bind and define a stack of logs. Colonial and early American sellers commonly arranged wood in piles eight feet long, four feet high, and four feet deep. Although dimensions varied regionally, the 128-cubic-foot standard became widely recognized. Today, legal definitions and allowed sales methods differ among jurisdictions, and loose wood may not equal a full cord.

Applications of cord [cd] unit

The cord remains common in firewood sales, especially in the United States and Canada. Suppliers may advertise full cords or face cords, the latter describing a stack with the same height and length but less depth. Buyers use the unit to compare quantities, estimate heating fuel, and plan storage, although local regulations may require wood sold by volume or weight.
