EU countries (er, those that switched to Euros ) are all metric.

In its defense, the US military and of course US scientists are all metric. (Military is even date format DD/MM/YYYY.)
As an American scientist, I can confirm this. The American scientific community uses the metric system in their work. The commercial and normal citizen use mile/foot/inch sometimes centimeter if we're feeling gutsy.

OK, maybe Celsius is only SI. Regardless, the US's continued use of Fahrenheit is contrary to the rest of the world and international standards, as is its use of MM/DD/YYYY. (Perhaps that date issue is more of a pet peeve of mine than anything.)
We (scientists) also use Celcius and Kelvin as well. But yes, most Americans use Fahrenheit. We're very stubborn =D
