Micro (symbol Âµ) is a unit prefix in the metric system denoting a factor of 10 â6 (one millionth). Confirmed in 1960, the prefix comes from the Greek Î¼Î¹ÎºÏÏÏ (mikros), mikrÃ³s meaning. Small the symbol for the prefix comes from The greek letter (Î¼). muor historical reasons, there are two different characters in Unicode, which appear slightly different in some fonts, although most fonts use the same glyph. The micro sign (Âµ) is encoded in the Latin-1 Supplement range identical to ISO/IEC 8859-1 (since 1985), at U+00B5 (Unicode 1.0, 1991).
