Hi Dave,

        Well, you asked:
What's the conversion factor to change miles per hour to furlongs per
fortnight?

Terms:
1 Mile = 5280 feet
1 furlong = 660 feet
1 fortnight = 24 x 14 = 336 hours

Calculations:
1 mile/hr = 5280 feet/hour
Hey guys, you're getting a little to serious about this.  I figured one
of the Canadian list member would do this off the top of his head with
all the experience up there. Like I remember back in the 60's, before
the metric invasion in the US, a friend of mine referred to his Crescent
wrench as a "Canadian Socket Set". It handled SAE, Whitworth and metric
all at once.
(ducking and running.....)

........1 furlong/fortnight = 660 feet/336 hours = ~1.96 feet/hour

Conversion:

For Furlongs/Fortnight to Miles/Hour   1.96/5280 = ~.00372   (multiply
by this factor)

For Miles/Hour to Furlongs/Fortnight  5280/1.96 = ~2688      (multiply
by this factor)

I wonder about the availability of the proper speedometer for this
application, and where are you going, anyway?
