It is not to be confused with the short ton, a unit of weight equal to 2,000 pounds (907.18474 kg) used in the United States, and in Canada before metrication, also referred to simply as a "ton".
A long ton is defined as exactly 2,240 pounds. The long ton arises from the traditional British measurement system: A long ton is 20 long hundredweight (cwt), each of which is 8 stone (1 stone = 14 pounds). Thus a long ton is 20 × 8 × 14 lb = 2,240 lb.
Unit equivalences
A long ton, also called the weight ton (W/T),[1]imperial ton, or displacement ton, is equal to:
2,240 pounds or 1,016 kilograms or 1.016 metric tons
Exactly 12% more than the 2,000 pounds of the North American short ton, because of the use of 20 long hundredweight (112lb) rather than 20 short hundredweight (100lb)
the weight of 35 cubic feet (0.99 m3)[2] of salt water with a density of 64 pounds per cubic foot (1.03 g/cm3)[1]
United Kingdom
To comply with the practices of the European Union, the British Imperial ton was explicitly excluded from use for trade by the United Kingdom's Weights and Measures Act of 1985.[3][4] The measure used since then is metric ton, identified through the word "tonne".
If still used for measurement then the word "ton", is taken to refer to an imperial or long ton.[5]
North America
In the United States, the long ton is commonly used in measuring the displacement of ships, the volume-to-carrying-weight of fuels, and in trade of baled commodities[1] and bulk goods like iron ore and elemental sulfur. The long ton was the unit prescribed for warships by the Washington Naval Treaty of 1922 – for example battleships were limited to a displacement of 35,000 long tons (36,000 t; 39,000 short tons).
International Trade
The long ton is traditionally used as the unit of weight in international contracts for many bulk goods and commodities.
Tonnage, volume measurement used in maritime shipping, originally based on 100 cubic feet (2.83 m3).
Tonne, also known as a metric ton (t), equal to 1,000 kg (2,205 lb) or 1 megagram.
