Suppose I cut the Earth into two halves .
Then  standing at equator and admiring it as a circle and just divide that circle into 360 degrees.
And I then divide that one degree to 60 minutes.
And a minute of arch is of course i would say that is equal to that  1 Nautical mile.
.
And it is used for all purposes that is Navigation and Air.
