About the Micrometer Symbol
The micro sign (µ, U+00B5) represents the SI prefix micro, denoting one millionth (10−6) of a unit. A micrometer (µm), also called a micron, equals one millionth of a metre — about the diameter of a human red blood cell (6–8 µm). The symbol derives from the Greek letter mu (μ, U+03BC), which is also used interchangeably in scientific typesetting. Other common micro units include the microgram (µg) used in pharmacology, the microlitre (µL) in laboratory measurement, the microsecond (µs) in electronics, the microampere (µA), the microwatt (µW), and the microfarad (µF) for capacitors. Unicode provides two separate code points: U+00B5 (micro sign, from Latin-1) and U+03BC (Greek small letter mu). For scientific work U+03BC is preferred, but U+00B5 is widely accepted and more easily typed. On Windows press Alt + 0181; on Mac press Option + M. In HTML use µ or µ.
