Common weight units

Milligram (mg)

Definition: A milligram (symbol: mg) is one thousandth of a gram and one millionth of a kilogram. It is a metric unit used for extremely small masses.

History/origin: The milligram comes directly from the metric system's decimal structure, making it a natural small subdivision of the gram for science, medicine, and laboratory work.

Current use: Milligrams are used for medicine dosages, vitamins, chemical compounds, and very small quantities of ingredients where grams would be too coarse.

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.
