1534 results about "Square meter" patented technology

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 m². Adding and subtracting SI prefixes creates multiples and submultiples; however, as the unit is exponentiated, the quantities grow geometrically by the corresponding power of 10. For example, a kilometre is 10³ (a thousand) times the length of a metre, but a square kilometre is 10 (10⁶, a million) times the area of a square metre, and a cubic kilometre is 10 (10⁹, a billion) cubic metres.
