The square mile (abbreviated as sq mi and sometimes as mi2) is an imperial and US unit of measure for an area equal to the area of a square of one statute mile.

It should not be confused with miles square, which refers to a square region with each side having the specified length. For instance, 20 miles square (20 × 20 miles) has an area equal to 400 square miles; a rectangle of 10 × 40 miles likewise has an area of 400 square miles, but it is not 20 miles square.

Land area measurements are originally recorded as whole square meters. Square meters are converted to square kilometers by dividing by 1000000; square kilometers are converted to square miles by dividing by 2.58999; square meters are converted to square miles by dividing by 2589988.
