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.

Gram (g)

Definition: The gram is a metric mass unit used for small everyday weights. It is exactly 0.001 kg, so 1,000 g make one kilogram.

History/origin: Early metric definitions linked mass to water volume, which made the gram a convenient smaller counterpart to the kilogram before modern physical standards took over.

Current use: G is used on kitchen scales, nutrition labels, coffee recipes, lab balances, jewelry listings, postal scales, packaged foods, and small product weights.
