Micro

From Free net encyclopedia

This article is about the 'micro-' prefix. Micro is also a semi-obsolete term for a microcomputer, as well as being slang for micromanagement in real-time strategy games.

micro- is a SI prefix in the SI system of units denoting a factor of 10⁻⁶ (one millionth). The symbol for it is the micro sign (µ). In circumstances where only the latin alphabet is available, it is customarily written using the letter u. E.g. um for µm, or uV for µV. Occasionally, micrograms are written as mcg.

Confirmed in 1960, the prefix comes from the Greek μικρός (transliterated: mikros), meaning small.

More generally, the prefix means "very small".
