ton (long)/cubic yard Unit Converter

Definition of ton (long)/cubic yard unit

Ton (long) per cubic yard is a unit of density expressing a mass of one imperial long ton distributed through one cubic yard of volume. It equals 2,240 pounds per 27 cubic feet, or approximately 83.0 pounds per cubic foot.

History of ton (long)/cubic yard unit

The unit combines two traditional measures: the long ton, established in British commerce as 2,240 pounds, and the cubic yard, derived from the English yard and standardized as 27 cubic feet. Long tons developed from medieval weighing practices and remained important in Britain, its empire, shipping, and heavy industry. Cubic yards became common for measuring bulk materials and excavation. Their combination was never a fundamental SI unit, but arose naturally in British and North American engineering, mining, construction, and shipping, where both mass and volume conventions were routinely used together.

Applications of ton (long)/cubic yard unit

Today, this unit appears mainly in bulk-material industries using imperial or U.S.-customary measurements. It can describe the density of coal, ore, aggregates, soil, dredged sediment, and other cargoes. Engineers and contractors may use it for estimating haulage loads, stockpile quantities, vessel cargo, excavation volumes, or material handling, although tonnes per cubic metre is preferred internationally.
