Thank you for the formula.

As to sexagesimal, is my face red.  I guess, as Readers Digest suggests, I
have to use it in conversation 10 times to make it mine.  It proves tough to
sneak into most conversations even once ;-)

My TI-30Xa allows one to enter degrees, minutes and seconds and convert to
decimal degrees with two keystrokes (2nd, DMS-DD).  For example 47d 16' 22"
would be entered as 47.1622 then converted to decimal degrees for
calculations.  It is also straight forward to convert back into sexagesimal
with 2nd, DD-DMS and does display the degree, minute, and second symbols on
the register.  I also like its straight forward  approach (and well marked
keys) for converting rectangular to polar and  and vise versa for solving
nav problems.

We will have to have a calculator shootout after our sextant shootouts ;-)
