The '''square metre''' ([[American and British English spelling differences#-re, -er|international spelling]] as used by the [[International Bureau of Weights and Measures]]) or '''square meter''' ([[American and British English spelling differences#-re, -er|American spelling]]) is the [[SI derived unit]] of [[area]] with symbol '''m<sup>2</sup>'''.<ref>{{citation | editor=David R. Lide | chapter=INTERNATIONAL SYSTEM OF UNITS | title=[[CRC Handbook of Chemistry and Physics]] | edition=90th | year=2010}}</ref>
Adding and subtracting [[SI prefix]]es creates multiples and submultiples; however, as the unit is [[exponentiate]]d, the [[quantities]] [[geometric growth|grow geometrically]] by the corresponding [[power of 10]]. For example, a [[kilometre]] is 10<sup>3</sup> (a [[thousand]]) times the length of a metre, but a square kilometre is 10<sup>3<sup>2</sup></sup> (10<sup>6</sup>, a [[million]]) times the area of a square metre, and a cubic kilometre is 10<sup>3<sup>3</sup></sup> (10<sup>9</sup>, a [[billion]]) cubic metres.
==SI prefixes applied==
The square metre may be used with all SI prefixes used with the metre.
