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 cwt, each of which is 8 stone (1 stone = 14 pounds). Thus a long ton is 20 Ã 8 Ã 14 lb = 2,240 lb.
In the UK, a ton is equal to 2,240 pounds. The international unit for mass is the kilogram; the toone (t) is a multiple of kg but is only an accepted unit in SI - the correct name is megagram. Short and long ton are obsolete units that make many confusions.
