Appearance move to sidebar hide From Wikipedia, the free encyclopedia SI prefix denoting 10 to the -3rd power Look up milli- in Wiktionary, the free dictionary. "Milli" redirects here. For other uses, see Milli (disambiguation).

Milli (symbol m) is a unit prefix in the metric system denoting a factor of one thousandth (10−3).[1] Proposed in 1793,[2] and adopted in 1795, the prefix comes from the Latin mille, meaning one thousand (the Latin plural is milia). Since 1960, the prefix is part of the International System of Units (SI).

Notes ^ Prefixes adopted before 1960 already existed before SI. The introduction of the centimetre–gram–second system of units was in 1873.
