Common weight units

Long ton (ton)

Definition: A long ton is a British imperial unit of mass equal to 2,240 pounds, or about 1,016.0469 kilograms.

History/origin: The long ton was part of the British imperial system and historically used in maritime trade and heavy industry before the widespread adoption of metric units.

Current use: Long tons still appear in some UK maritime, industrial, and historical contexts, though they are far less common than metric tons today.

Atomic mass unit (u)

Definition: The atomic mass unit is a tiny scientific mass unit. One unified u is defined as 1/12 of the mass of a neutral carbon-12 atom.

History/origin: Atomic-scale work needed a mass reference that matched atoms more naturally than kilograms, so carbon-12 became the basis for a unified relative unit.

Current use: U appears in atomic weights, isotope masses, molecular formulas, mass spectrometry, nuclear data, biochemistry, and particle or molecular science references.
