Units explained
Milligram
A milligram (mg) equals one-millionth of a kilogram, or 0.001 gram.
From the SI prefix 'milli-' (from Latin 'mille', thousand).
Standard for medicine dosing, nutrition labels, and fine jewelry.
Part of the original metric system of 1795.
Poundal

Defined in the foot-pound-second absolute system in the late 19th century.
Early 20th-century physics and engineering.
Introduced in the absolute FPS system as an alternative to gravitational units.
