<font face="Arial, Helvetica, sans-serif">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?<br>

Subject: [Proj] Terminology: what should I call 60 nautical miles?<br>
<br>
<div id="AOLMsgPart_0_ef7d995d-f581-415b-9349-81de68d35aa1" style="margin: 0px; font-family: Tahoma,Verdana,Arial,Sans-Serif; font-size: 12px; color: rgb(0, 0, 0); background-color: rgb(255, 255, 255);">
<pre style="font-size: 9pt;"><tt>Hello,<br>
I would like a term for the length unit that is 60 nautical miles. <br>
<br>
This length unit would approximate one degree of <br>
arc distance, in the same way as one nautical mile <br>
approximates one minute of arc distance.<br>
<br>
I have thought of the phrase "degree of arc distance" <br>
(which I think agrees, more or less, with how Snyder uses this phrase)<br>
but some of my colleagues dislike it. <br>
<br>
I have also thought of the phrase "exēntanautical mile",<br>
from Greek "exēnta" = 60, but... <br>
