The geographical mile, or U.S. survey mile, is a unit of length determined by 1 minute of arc along the Earth's equator, approximately equal to 1855 metres (6087.15 international feet). It is not the same as the more commonly used statute mile, which is 5280 feet, or the nautical mile which is 1 minute of arc along a great circle of the Earth (1852 metres, 6076.1 feet). The U.S. survey mile is used almost exclusively by the U.S. Coast and Geodetic Survey.
