A sea mile is a unit of length defined as exactly 1852 meters (about 6076.1 feet or 1.1508 statute miles).

Historically, it was defined as one minute of latitude, which is equivalent to one sixtieth of a degree of latitude. Today it is an SI derived unit, being rounded to an even number of meters and remains in use for both air and marine navigation and for the definition of territorial waters.

The derived unit of speed is the knot, defined as one nautical mile per hour. The geographical mile is the length of one minute of longitude along the Equator, about 1855.325 m on the WGS 84 ellipsoid.
