1. Geographical mile

   The geographical mile is an international unit of length determined by 1 minute of arc—1/60 degree—along the Earth's equator. For the international ellipsoid 1924 this equalled 1855.4 metres. The American Practical Navigator 2017 defines the geographical mile as 6087.08 feet (1855.342 m). Greater precision depends more on choice of ellipsoid than on more careful measurement: the length of the equator in the World Geodetic System WGS-84 is 40075016.6856 m, which makes the geographical mile 1855.3248 m, while the IERS Conventions (2010) takes the equator to be 40075014.1723 m, making the geographical mile 1855.3247 m, 0.1 millimetres shorter. In any ellipsoid, the length of a degree of longitude at the equator is thus exactly 60 geographical miles. The shape of the Earth is a slightly flattened sphere, which results in the Earth's circumference being 0.168% larger when measured around the equator as compared to through the poles. The geographical mile is slightly larger than the nautical mile (which was historically linked to the circumference measured through both poles); one geographic mile is equivalent to approximately 1.00178 nautical miles.

1. geographical mile

   A geographical mile is a unit of measurement used in geography, equivalent to one minute of latitude on the Earth's surface, approximately 1,852 meters or 6,076 feet. It is typically used in navigation, geography, and cartography. It's important to note that it slightly varies depending on the latitude as the Earth is not a perfect sphere but an oblate spheroid.

1. Geographical mile

   The geographical mile is a unit of length determined by 1 minute of arc along the Earth's equator. For the 1924 International Spheroid this equalled 1855.4 metres. Any greater precision depends more on choice of standard than on more careful measurement: the length of the equator in the World Geodetic System WGS-84 is 40,075,016.6856 m which makes the geographical mile 1855.3248 m, while the International Astronomical Union standard IAU-2000 takes the equator to be 40,075,035.5351 m making the geographical mile 1855.3257 m, almost a millimetre longer. It was closely related to the nautical mile, which was originally determined as 1 minute of arc along a great circle of the Earth, but is nowadays defined as exactly 1852 metres. The US National Institute of Standards and Technology notes that: "The international nautical mile of 1 852 meters was adopted effective July 1, 1954, for use in the United States. The value formerly used in the United States was 6 080.20 feet = 1 nautical mile." A separate reference also identifies the geographic mile as being identical to these international nautical miles. The unit is not used much, but is cited in some United States laws. While debating what became the Land Ordinance of 1785, Thomas Jefferson's committee wanted to divide the public lands in the west into “hundreds of ten geographical miles square, each mile containing 6086 and 4-10ths of a foot” and “sub-divided into lots of one mile square each, or 850 and 4-10ths of an acre”.
