The square metre (international spelling as used by the International Bureau of Weights and Measures) or square meter (American spelling) is the SI derived unit of area with symbol m 2 .

The SI has special names for 22 of these derived units (for example, hertz, the SI unit of measurement of frequency), but the rest merely reflect their derivation: for example, the square metre (m 2 ), the SI derived unit of area; and the kilogram per cubic metre (kg/m 3 or kg⋅m −3 ), the SI derived unit of density.

### Area
