Yay, a fellow SI nazi! :) I remember being helplessly confused when I moved to the US before I figured out that what the Americans call a "calorie" is actually a kcal. A cal is the scientific unit, normally used with the k prefix, and in Sweden food labels (and even our school home economics textbook) use kcal (and KJ). I'm kind of used to the US using weird-ass units by now, but the fact that they just decided to drop the prefix on some unit (presumably because they didn't want to subject the public to learning that k means thousands) is too much.
