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.
- One minute of latitude is one nautical mile (1.15 miles, 1.85 kilometers) <br /> - One minute of longitude <b>at the equator</b> is also one nautical mile, but decreases as you move toward the poles.<br /><br />---<br />You can find this by taking the Earth's circumference and divide it with number of minutes.
