Metric Ton

The metric ton (or tonne, symbol t) is a unit of mass equal to 1,000 kilograms (1,000 kg) or 1 megagram (1 Mg). It is part of the metric system but is not an SI unit. However, it is accepted for use with the SI due to its widespread application in measuring large masses, such as in industry and transportation.

Origin:

The metric ton was introduced in the 1790s during the creation of the metric system in France. It was established as a convenient way to represent large quantities of mass, aligning with the decimal-based nature of the system. The term "tonne" is derived from the Old French word "tonne", meaning a large cask or barrel, reflecting its use in measuring heavy loads. Over time, it became a standardized unit used globally in fields like shipping, agriculture, and environmental science.

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.
