A square mile is defined as the area of a square with sides one mile in length.
The definition of a mile is as follows:
A mile is any of several units of distance, or, in physics terminology, of length. Today, one mile is mainly equal to about 1609 m on land and 1852 m at sea and in the air, but see below for the details. The abbreviation for mile is 'mi'. There are more specific definitions of 'mile' such as the metric mile, statute mile, nautical mile, and survey mile. On this site, we assume that if you only specify 'mile' you want the statute mile.
The decare is a unit for the measurement of area, generally used for land area. One decare (from deka, 10 and are) is the same as 10 ares, which is the same as 1000 square metres. Though its base unit, the are, was defined by older forms of the metric system, it is not part of the modern metric system, the International System (SI). It is accepted, but not encouraged, for use with the SI.
The decare is not widely used, except in Norway and many of the formerly Ottoman countries; it corresponds roughly to the Byzantine stremma and the Ottoman donum, and exactly to the metric stremma and donum.
