About these units
Atomic Mass Unit (u)
The atomic mass unit (u) is defined as exactly 1/12 the mass of a neutral carbon-12 atom, which makes it approximately 1.66053906660 × 10⁻²⁷ kilograms. This definition allows scientists to express atomic and molecular masses in a convenient, intuitive scale that aligns with the structure of the periodic table. By anchoring the unit to carbon-12, chemists and physicists gained a universal reference point that harmonizes molecular weight, relative isotopic abundance, and mass spectroscopy results. The atomic mass unit effectively normalizes the complexity of atomic masses into whole-number or near-whole-number values for most nuclei. In chemistry, u is indispensable for calculating molar masses, reaction stoichiometry, and isotopic compositions. It is also used across nuclear physics, astrophysics, and biophysics, demonstrating the universality of atomic-scale measurement.
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 While replaced by metric units in the UK, this unit persists in historical documents, trade archives, and older engineering references.
