Comparison of 1 square metre with some Imperial and metric units of area The square metre (international spelling as used by the International Bureau of Weights and Measures) or square meter (American spelling) is the unit of area in the International System of Units (SI) with symbol m. It is the area of a square with sides one metre in length.

Adding and subtracting SI prefixes creates multiples and submultiples; however, as the unit is exponentiated, the quantities grow exponentially by the corresponding power of 10. For example, 1 kilometre is 10 (one thousand) times the length of 1 metre, but 1 square kilometre is (10) (10, one million) times the area of 1 square metre, and 1 cubic kilometre is (10) (10, one billion) cubic metres.
