Stone: (abbreviation: st) is a unit of mass that is primarily used in the United Kingdom and Ireland to measure body weight. Although it is considered part of the imperial system, its use is largely limited to a few specific contexts today.
The stone as a unit of weight has been used since antiquity, with its value varying regionally depending on the commodity being measured. It became standardized in the 14th century in England, where it was fixed at 14 pounds for weighing wool, a major commodity at the time. Ton (Imperial): also known as the "long" ton, is a unit of weight used in the imperial system, which was historically common in the United Kingdom and some Commonwealth countries. It is larger than the US ton (short ton) but slightly smaller than the metric ton.
1 imperial ton = 2,240 pounds
1 imperial ton = 1,016.05 kilograms (kg) in the metric system
