[Proj] Terminology: what should I call 60 nautical miles?

[strebe at aol.com]

Your original instinct seems correct: one degree of arc. That is, after all, the entire reason you are interested in 60 nautical miles, is it not? Because it equates to a degree of arc on the spherical model? If you apply some other terminology to it then you have destroyed the reason for the unit. Or have I missed some other significance?

Hello,
I would like a term for the length unit that is 60 nautical miles.  

This length unit would approximate one degree of 
arc distance, in the same way as one nautical mile 
approximates one minute of arc distance.

I have thought of the phrase "degree of arc distance" 
(which I think agrees, more or less, with how Snyder uses this phrase)
but some of my colleagues dislike it. 

I have also thought of the phrase "exēntanautical mile",
from Greek "exēnta" = 60, but...
