Milligrams to Grams Converter

To convert a measurement in milligrams to grams, multiply the value by 0.001. The conversion factor comes from the relationship between both units and the kilogram.

For example, to convert 5 mg to grams: 5 × 0.001 = 0.005 g.

A milligram is a metric unit of mass equal to one thousandth of a gram (0.001 g) or one millionth of a kilogram. Part of the original metric system, the milligram derives from the Latin 'mille' (thousand). It became indispensable in pharmacy and medicine, where drug doses are almost always expressed in milligrams.

Common uses of milligrams include: Medication and supplement dosages; Nutrient amounts on nutrition labels (sodium, vitamins); Laboratory chemistry and analytical work; Gunpowder and reloading measurements.

A gram is a metric unit of mass equal to one thousandth of a kilogram (0.001 kg) or about 0.035 ounces. Defined in 1795 as the mass of one cubic centimeter of water at the temperature of melting ice.
