Yes. No one ever ever gives a shit how many feet are in a NM. That conversion is never made.

No one cares a out miles/hour or km/h either. Feet/miles/km never come up on the GPS or maps.

Ft/sec does actually matter but that's vertical speed. It's actually very nice they're a completely separate unit because you're not going to confuse someone else by saying I'm going 3m/sec and they have to worry and think if they're talking about vertical or horizontal speed.

GPS is always in degrees and minutes. One minute is exactly one nautical mile. All the maps are scaled so that's true. If you can fly about 120knots and you want to fly from 38n to 39n that's about half an hour of flying because 38 to 39 is 1 degree, and one degree is 60 minutes is 60 NM. One knot is one nm/h.
