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.

Adding and subtracting [[SI prefix]]es creates multiples and submultiples; however, as the unit is [[exponentiate]]d, the [[quantities]] [[exponential growth|grow exponentially]] by the corresponding [[power of 10]]. For example, 1 [[kilometre]] is 10<sup>3</sup> (one [[thousand]]) times the length of 1 metre, but 1 square kilometre is (10<sup>3</sup>)<sup>2</sup> (10<sup>6</sup>, one [[million]]) times the area of 1 square metre, and 1 cubic kilometre is (10<sup>3</sup>)<sup>3</sup> (10<sup>9</sup>, one [[billion]]) cubic metres. |
