In this particular instance, however, re-thinking 75°15'00" N as 75.25
goes against decades (if not hundreds of years) of accumulated use of the
former idiom, accepted by virtually all the people working in that
particular field.  The switch from a notation such as 75°15'00" N and 75
15 00 N is minor; the switch to 75.25 requires some real "CPU time" for a
human.

Similarly, 14:45 and 2:45 p.m. are common, interchangeable idioms; 885 is
not. 885?  That's the number of minutes past midnight for that particular
time. Given the current discussion, that was instantly obvious to you, but
you'd never think of using that idiom in any ordinary documents or
correspondence involving times.
