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.
Degrees and Minutes The distance between degrees of longitude is about 60 nautical miles at the equator. It is less further north or south as the longitude lines converge towards the poles. Degrees of latitude are always 60 nautical miles apart. At the equator, a grid of 1Â° of longitude by 1Â° of latitude covers about 3,600 square miles. For greater precision, degrees are divided into 60 minutes ( ' ) - of distance, not time.
