I am so embarrassed by America and our failure to convert to the metric
system.   While the whole rest of the world has adopted our language as the
international language, we cant even convert to the universal system of
units!  That is really lame.

Other than the fact that feet does seem to work better than meters for the
airspace system (though that can eventually be worked out), the rest of
aviation should have changed by now.  Altimeter settings should be in mm Hg,
all temps in C.  Speed limits and speedometers in all cars should be in Km.
Postal weights should be in Kg...

Sigh,
Dave Leonard
