I am so embarrassed by America and our failure to convert to the = metric=20 system.   While the whole rest of the world has adopted our = language=20 as the international language, we cant even convert to the universal = system of=20 units!  That is really lame.

Sigh,

Aviation in the US uses a strange mix of = units, AWOS=20 reports altitudes

Charly,
 
I lerned to use a P for lead, = which stands=20 for PLUMBUM (latin?).
