Long Ton

The long ton (symbol lt) is a unit of mass primarily used in the United Kingdom and some Commonwealth countries. It is equal to 2,240 pounds or approximately 1,016.05 kilograms. The long ton is part of the imperial system and is larger than both the short ton (used in the U.S.) and the metric ton.

Origin:

The long ton originated in medieval England as a standardized measure for trade, particularly for goods like coal and other bulk materials. It was defined as 20 long hundredweight, with each long hundredweight being 112 pounds. This measure became part of the British Imperial System in 1824 and has been widely used in maritime and industrial contexts, especially in the UK, before the metric system was more broadly adopted.

Stone (UK)

The stone (st) is a unit of mass used primarily in the United Kingdom and Ireland to measure body weight. It is defined as 14 pounds or approximately 6.35 kilograms. The stone is still commonly used in the UK for personal weight, especially in everyday contexts like medical and fitness settings.

Origin:

The stone has ancient origins, dating back to the medieval period. Historically, the weight of a stone varied depending on the commodity being measured, ranging from 5 to 30 pounds. For example, in England, the stone was used to measure wool, and different types of goods had their own stone weights. In 1300, a standardized 14-pound stone was adopted for use in the wool trade. Over time, this 14-pound definition became the standard, and the stone was widely used in the UK for measuring body weight, a tradition that continues today.
