I now make parts for different people who e-mail/fax me drawings so I
can quote on them.
Some parts are such that I can't tell what they are or what they're
the purpose of them are.
Sometimes I see dimensions as obviously imperial ones, sometime it is
hard to tell, especially when I have NO clue what these parts are.
Personally, I don't give a rat's ass what system is used as I work in
both metric and imperial.
But what seems to be the reason for the US hold-out to stay with an
archaic system?

Ok, What ia half of 5.3 mm?


Irrelevant if you've truly converted to metric. Just like learning a
foreign language. When you've truly gotten it, you don't translate in your
head, you *think* in the language in which you're speaking. No different
here. 5.3mm=5.3mm. period.
