Are you sure that you're an American? The american spelling is
"gram", not "gramme", and I've heard many Americans pronounce kilo
"kill-low". Also many road signs in my home-town (Louisville, KY) are
marked in kilometers.
Also, have you ever bought a 9-volt battery? Or a 60 watt
light-bulb? Or a computer who's processor speed is measured in hertz?
All of these have are metric (or SI to be precise) units.
Also, when measuring time, don't you use the second and it's
derrived units?

I don't know where you went to school, but in my high-school, all of
my math courses used radians.

Oh yes there is, and you'd damn well better believe that it's important. If
you had ever designed ECL or CML logic, you'd either know that it was, or
you'd have failed.
So, exactly what part of "What part of engineer don't you understand," don't
you understand?
Bernie was right, Aaron. Stick to software.

Alternatively, you can have your firewall return a ping response
for EVERY legal address behind your firewall.

Lawrence is correct, and so are you, save for your first eleven words.
Lawrence has an admirably elegant economy with words which I would do
well to emulate. (Fear not - I have no immediate plans to mitigate my
exuberant verbosity.)
