    Re: Name for sixty nautical miles

    Of course, the problem with all of these proposals is not one of them will appear in any reference text.  Your students will not find the name and perhaps be even further confused.

    You asked for us to invent a name for one degree along a great circle.  Now that the merriment has ended, we can observe that it does have a name, referenced in texts.  It's "One degree on a great circle"! 

    That's clear to me as it should be to anyone who first understands what a great circle is.  You wish to then further that understanding by associating one degree along the great circle with 60 nautical miles.  Additionally, you want some memorable mnemonic to help your students. 

    The names presented herein might work. But still won't appear in period text books.  And therein lies the rub.

    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.
