40075.02 / 360 / 60 = 1.8553 km. One minute of longitude on equator is 1.8553 km. Please note - on equator (i.e. on 0 degree of latitude)! Because the length of parallels decrease toward the north or south pole, the length (in km or miles) of minute of longitude differs for different latitudes.
Lesson Summary. Latitude is the angular distance of a place north or south of the Equator in degrees. A latitude of zero degrees is on the Equator of the Earth. Ninety degrees north is the North Pole, and 90 degrees south is the South Pole. Longitude is the angular distance of a place east or west of the meridian at Greenwich, England. With these two numbers, any point on the Earth's surface can be located.
