The millimetre (American spelling: millimeter, symbol mm) is a unit of length in the metric system, equal to one thousandth of a metre, which is the current SI base unit of length.

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 only with East Asian fixed-width CJK fonts, because they are equal in size to one Chinese character.
