A good wag is: Mach # roughly equals NM per minute (ie .85 is about
8.5 nm per minute). Convert this to TAS by multiplying by 60 (in this
example, about 510 knots true). As for converting NM to statute miles,
you're on your own, I think a NM is about 6100 ft.
This is a pilot-friendly conversion, far from exact, but useful and
close enough for me!
