The ton is a unit of measure. It is used principally as a unit of mass. The ton (any definition) is the heaviest unit of weight typically used 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 m 3 ) in capacity.
It can also be used as a unit of energy, expressed as an equivalent of coal burnt or TNT detonated. It is derived from the tun , the term applied to a cask of the largest capacity. This could contain a volume between 175 and 213 imperial gallons (210 and 256 US gal; 800 and 970 l), which could weigh around 2,000 pounds (910 kg) and occupy some 60 cubic feet (1.7 m 3 ) of space.
