There are three similar units of mass called the ton: 1. long ton (simply ton in countries such as the United Kingdom which formerly used the Imperial system of weights and measures) is a weight ton or gross ton, and is 2,240 pounds (exactly 1,016.0469088 kg). In the UK and most of the areas which used the Imperial system, the metric ton (1,000 kg), which is conveniently very similar to—less than 2% difference—is the only form of ton legal for trade. - In the iron industry in the 17th century and 18th century, a ton shortweight was the standard 2,240 lb, whereas a ton longweight was 2,400 lb (the hundredweight being 120 lb). - The long ton is used for petroleum products such as aviation fuel. - Deadweight ton (abbreviation 'DWT' or 'dwt') is a measure of a ship's carrying capacity, including bunker oil, fresh water, ballast water, crew and provisions. It is expressed in metric tons (1,000 kg) or long tons (2,240 pounds, about 1,016 kg). This measurement is also used in the U.S. tonnage of naval ships. - Increasingly, metric tonnes are being used rather than long tons in measuring the displacement of ships. See tonnage. 2. short ton (usually called simply ton in North America or sometimes called a net ton) = 2,000 lb (about 907.18474 kg). - Harbour ton used in South Africa in the 20th century, equal to 2000 pounds or one short ton. 3. The metric ton, or tonne, is 1,000 kg (or 1 Mg) or approximately 2,204.6 pounds. Both the long ton and the short ton are composed of twenty hundredweights, each having different values for the hundredweight (112 and 100 pounds respectively). Prior to the 15th century in England, the ton was composed of 20 hundredweights, each of 108 lb, giving a ton of 2,160 pounds.
