Centimetre

cm redirects here, alternate uses: cm (disambiguation)

A centimetre (American spelling: centimeter, symbol: cm) is an SI unit of length.

One centimetre is:

• one-hundredth of one metre
• one-tenth of a decimetre
• ten millimetres.

Unicode has symbols for "cm" (㎝), for square centimetre (㎠) and for cubic centimetre (㎤); however, they are intended to be used only with East Asian fixed-width CJK fonts, so that they take up exactly as much space as one Chinese character does.

millimetre << centimetre << decimetre
