WebOne nautical mile equals 1852 meters. Historically it was defined as one minute of arc along the meridian or 1/(60×180) of a meridian. This allowed for simplified calculations of latitude because every 60 nautical miles were one degree of latitude. When calculating speed using nautical miles, often knots are used as units.
