	The '''geographical mile''' is a unit of length determined by 1 [[minute\|minute of arc]] along the [[Earth]]'s [[equator]], approximately equal to 1855.325 [[metre]]s (6087.025 international [[foot (length)\|feet]]). 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.
