Long ton, also known as the imperial ton or weight ton, is the name for the unit called the  ton  in the avoirdupois or Imperial system of measurements standardised in the thirteenth century that is used in the United Kingdom and several other Commonwealth countries alongside the French metrication invented in 1799.he long ton arises from the traditional British measurement system: A long ton is 20 hundredweight, each of which is 8 stone, which is defined as 14 pounds.
Where accuracy is required the correct term must be used, but for many purposes this is not necessary: the metric and long tons differ by only 1.6%, and the short ton is within 11% of both. The ton is the heaviest unit of weight referred to in colloquial speech. The term ton is also used to refer to a number of units of volume, ranging from 35 to 100 cubic feet (0.99 to 2.83 m3) in capacity. It can also be used as a unit of energy, expressed as an equivalent of coal burnt or TNT detonated. In refrigeration, a ton is a unit of power, sometimes called a ton of refrigeration.
