Tonne

The tonne (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 tonne 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.

Dalton

The dalton (Da) or unified atomic mass unit (u) is a unit of mass used to express atomic and molecular weights. It is defined as one twelfth of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state, and it is approximately equal to 1.66053906660 × 10⁻²⁷ kg.

Origin:

The dalton is named after the English chemist and physicist John Dalton, who developed the atomic theory of matter. The unit was adopted in 1961 by the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP) to provide a standardized unit for atomic and molecular weights.
