The millimetre (American spelling: millimeter; SI unit symbol mm; informal abbreviation: mil[1]) is a unit of length in the metric system, equal to one thousandth of a metre, which is the SI base unit of length.
It is equal to 1,000 micrometres and 1,000,000 nanometres. There are 25.4 mm in one inch.
[edit] Unicode symbols
For the purposes of compatibility with Chinese, Japanese and Korean (CJK) characters, Unicode has symbols for:
- millimetre (㎜) - code 339C
- square millimetre (㎟) - code 339F
- cubic millimetre (㎣) - code 33A3
They are useful for East Asian fixed-width CJK typography, because they are equal in proportion to one Chinese character.
