You are approaching the problem from the pilot's perspective

I've always tried to do my X-country flight planning using furlongs
per fortnight. Tough to find the conversion factor on my E-6B though.

That's just one of the many advantages of electronic flight computers, but those
spoilsports at the FAA refuse to play along. Personally, I think rather than using Mach
we should begin the changeover to using fractions of 'c' (SI or English makes no never
mind, except for the engineers). We'll need to eventually, and (judging by the rate at
which the US has accepted converting to metric) we should have nearly accepted the new
units around the time we're likely to need them;-)
