This discussion reminds me of the Air Canada passenger jet from Toronto 
to Vancouver that was forced down at Brandon Manitoba when the fuel ran 
out..  Seems the fuel was loaded in pounds rather than kilograms.

I don't suppose there is any possibility that we will soon be measning 
angles in radians rather than degrees is there?  2 pi radians = 360 degrees.
