Micro
From Wikipedia, the free encyclopedia.
This article is about the 'micro-' prefix. Micro is also a semi-obsolete term for a microcomputer.
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.
Confirmed in 1960, the prefix comes from the Greek μικρός (transliterated: mikros), meaning small.
More generally, the prefix means "very small"
