Grams (g)

Definition

A gram (g) is a metric unit of mass equal to one thousandth of a kilogram. It was originally defined as the mass of one cubic centimeter of water at 4°C.

History

The gram was introduced in 1795 as the base unit of mass in the original metric system. Though the kilogram later replaced it as the SI base unit, the gram remains the most commonly used unit for everyday small-scale measurements.

Current use

Grams are used worldwide for food labeling, cooking recipes, postal weighing, jewelry and gemstone measurement, and small-scale scientific work. Nutritional information on food packaging is universally expressed in grams.

Milligrams (mg)

Definition

A milligram (mg) is a metric unit of mass equal to one thousandth of a gram (0.001 g) or one millionth of a kilogram.

History

The milligram derives from the gram, established during the French Revolution as part of the metric system in 1795. It became essential with the development of analytical chemistry and pharmacology in the 19th century.

Current use

Milligrams are the standard unit for medication dosages, nutritional supplement amounts, vitamins, blood chemistry measurements, and chemical analysis. Nearly all pharmaceutical labels specify quantities in milligrams.
