This, however, varies between 1843 m (6046.58793 ft) at the equator, 1853 m (6079.3963 ft) at 45°N and S latitude, and 1862 m (6108.9238 ft) at the poles because the earth is an oblate spheroid. However, for the purpose of navigation, the International Nautical Mile of 1852 m (6076.1033 ft) has been adapted as the standard for air navigation.See NASA Management Instruction See NAUT MInautical mile
