About these units
Hundredweight (UK) (cwt (UK))
The British hundredweight equals 112 pounds (50.802345 kg). The extra 12 pounds derive from England's historical use of a 14-pound stone. The British hundredweight was used across the former British Empire for trade, taxation, and freight classification. It scales into the long ton (20 cwt = 1 long ton), forming a fully coherent system within imperial measurements. While replaced by metric units in the UK, this unit persists in historical documents, trade archives, and older engineering references.
Dalton (Da)
The Dalton is numerically identical to 1 atomic mass unit and is commonly used in biochemistry and molecular biology, especially for expressing the masses of proteins, peptides, and macromolecules. While "u" is often preferred in physics and chemistry, the Dalton became the standard in biological sciences because it fits neatly into descriptions of amino acids, nucleotides, and biomolecular complexes. For example, a typical protein may have a mass of 50 kilodaltons (kDa). The adoption of the Dalton helped unify communication across genomics, proteomics, and structural biology. As molecular biology expands into nanotechnology and synthetic biology, the Dalton remains a central unit for describing the building blocks of life.
