Leave it to the wisdom of Ancient India-Indians
Twelve spokes, one wheel, navels three.
Who can comprehend this?
On it are placed together
three hundred and sixty like pegs.
They shake not in the least.
— Dirghatamas, Rigveda 1.164.48
Found the above on Wikipedia, makes sense if you can figure it out.
The Wikipedia article on Degrees (angle) the article also references the proof that six chords equal a 360-degree circle. And that the length of said chord is one-sixtieth of the arc defined by said chord.
There is also the 60-1 Rule or the 1 in 60 rule as Wikipedia lists it. All told a Nautical Mile is what defines the chord.
Ergo, what to call it? It is already define 60:1; 60-1; or 1 in 60 all truths and proven truths which tell us why one degree is equal to one nautical mile.

If memory serves, a Cable is 100 Fathoms and a League is 10 Cables or 1000 Fathoms.= 1 nautical mile
Different countries have had different definitions of a league, and a land league is often shorter than a sea league, but it always has been considered to be several miles.
In the UK and the US, a sea league has generally been equated with three nautical miles.
