Milligramm

Milligramm is the unit of mass equal to one thousandth of a gram. The symbol is mg. It is a derived unit in the metric system, formed from the prefix milli- (10^-3) and the gram, the SI base unit of mass. In German-language use, the term is written Milligramm, reflecting the spelling conventions of that language; in English contexts, the corresponding term is milligram.

Milligramm is used for small masses where grams are impractical, especially in medicine, pharmacology, chemistry, and laboratory science. Many dosages and measurements are expressed in milligrams, with common examples including tablet dosages and chemical masses. Conversions are straightforward: 1 g = 1000 mg, 1 mg = 0.001 g, and 1 mg = 1000 micrograms (µg). Achieving accurate measurements at the milligram scale requires precise instruments, such as analytical balances and well-calibrated scales, along with control of environmental factors like air currents and buoyancy.

As an SI unit, milligramm/milligram is a standard unit of mass for small quantities. Note that mass is a measure of the amount of matter, while weight is the force exerted by gravity on that mass; in everyday usage, mg denotes mass, not weight.
