Convert Square Meter to Square Mile
Please provide values below to convert square meter [m^2] to square mile [mi^2], or vice versa.
Square meter
Definition: The square meter, or square metre (symbol: m2), is an SI (International System of Units) derived unit of area. It is defined as the area of a square with side measures of one meter, where the meter is currently defined as the distance traveled by light in 1/299 792 458 of a second when expressed in the unit m·s-1, where the second is defined in terms of the cesium frequency, ΔνCs.
History/origin: Area is commonly represented in the form of a square with sides of a specific unit of length, written as "square" followed by the chosen unit of length. The square meter is one of many such units and is derived from the area of a square with sides of one meter.
Current use: The square meter is the SI unit of area, though it is considered an SI derived unit rather than an SI unit. It is most often used to measure land area such as rooms, houses, and large plots of land. As with other SI units, the standard prefixes can be applied to the square meter to signify decimal multiples. Examples of this include the square decameter, square hectometer, and square kilometer. However, these larger measurements are typically not used, as the square meter is already a fairly sizeable measurement, and these prefixes would be referring to large areas that are not commonly referenced. Note that the square meter and its multiples and submultiples are squared, making a square decameter 10,000 times the size of a square meter even though a decameter is 100 times the size of a meter.
Square mile
Definition: The square mile (symbol: sq mi or mi2) is a unit of area in the imperial and United States customary (UCS) systems of units. It is defined as the area of a square with side lengths of one statute mile (5,280 feet). A square mile is a large area that is equal to 27,878,400 square feet, 3,097,600 square yards, and 640 acres.
History/origin: Area is commonly represented in the form of a square with sides of a specific unit of length, written as "square" followed by the chosen unit of length. The square mile is one of many such units and is derived from the area of a square with sides of one mile.
Current use: Square miles are used when the measurement involves large scales such as country sizes. It can be used when referencing population studies, such as a measurement of total population per square mile. As an imperial and USC unit, it is most commonly used in countries that use these systems of measurement. In countries that have adopted the International System of Units, the square meter (and its subsequent multiples and submultiples) is the preferred system of measurement.
