Aps, 1 nautical mile is equal to 1
minute of longitude at the equator which is pretty much equal to minutes of latitude any where on the globe. There are 60 minutes per degree. If it were equal to one degree the earth would have a circumference of 360 nautical miles, much smaller than the actual circumference which is about 21,600 nautical miles.
