Micro ( Greek letter μ, mu, non- italic) is a unit prefix in the metric system denoting a factor of 10 −6 (one millionth ). [1] Confirmed in 1960, the prefix comes from the Greek μικρός ( mikrós ), meaning "small". It is the only SI prefix which uses a character not from the Latin alphabet.
Aug 11, 2014 · The symbol for micro is the Greek letter μ. 1 micrometer is written as 1 μm. The distance between the Earth and the Moon is about 384,000,000 meters. The Mega prefix (symbol M) means one million, so you could say the distance is 384 Megameters or 384 Mm. Substituting the metric prefix can make doing calculations easier in your head.
