What is a Kilogram and a Ton (UK)?

The kilogram is the base unit of mass in the International System of Units (SI). It is defined based on the fixed numerical value of the Planck constant.

The UK Ton, also known as the Long Ton or Imperial Ton, is a unit of mass in the Imperial system. It is defined as 2,240 pounds, which is equivalent to 1,016.0469088 kilograms.

Note: The Kilogram is part of the metric (SI) system, primarily used globally in science and trade. The Ton (UK) belongs to the imperial/US customary system.

History of the Kilogram and Ton (UK)

Originally defined as the mass of one liter of water. Later, it was represented by the International Prototype of the Kilogram (IPK), a platinum-iridium cylinder. In 2019, the definition was changed to be based on fundamental physical constants.

The term "ton" originates from the "tun," a large cask used in the wine trade. The long ton was standardized in the British Weights and Measures Act of 1824 and was historically used in the UK and Commonwealth countries for trade and shipping.
