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.

Ton (assay) (UK)

The ton assay (UK) is a unit of mass used in the United Kingdom, primarily in the context of assaying precious metals. It is equal to 29.16666667 kilograms or approximately 64.58333333 pounds. The ton assay is used to measure the mass of ore samples in the process of determining the content of precious metals.

Origin:

The ton assay originated in the United Kingdom as a unit of mass for assaying precious metals. It was defined as 29.16666667 kilograms or approximately 64.58333333 pounds. The term "ton assay" comes from the practice of assaying, which is the process of determining the content of precious metals in ore samples. The ton assay is used in the United Kingdom for this purpose.
