Ton (Long)
A long ton, also known as the imperial ton or UK ton, is a unit of weight equal to 2,240 pounds or 1,016.0469 kilograms.
History/Origin
The long ton originated in the United Kingdom as a standard measurement for large quantities of goods and materials, particularly in shipping and trade, during the 19th century. It was used alongside other imperial units before the adoption of the metric system.
Current Use
Today, the long ton is primarily used in the United Kingdom and some Commonwealth countries for measuring large quantities of freight, cargo, and in certain industrial contexts. It is less common internationally, having been largely replaced by the metric ton (tonne).
Atomic Mass Unit
The atomic mass unit (u) is a standard unit of mass used to express atomic and molecular weights, defined as one twelfth of the mass of a carbon-12 atom.
History/Origin
The atomic mass unit was introduced in the early 20th century to provide a convenient scale for atomic weights. It was originally based on the mass of hydrogen but was later standardized to be one twelfth of the mass of a carbon-12 atom, which was adopted as a reference in 1961 by the IUPAC.
Current Use
The atomic mass unit is widely used in chemistry and physics to express atomic and molecular masses, facilitating calculations in molecular chemistry, nuclear physics, and related fields.
