#1: Products that use calories instead of kilo-calories. It can get terribly confusing if there are diet products being advertised as only 100 calories, and I have to go and figure out whether or not they actually mean 100 kilo-calories or 0,1 kilo-calories. Why should this have nothing do with me? I'm not dieting. #2: female hair colouring products having lying boxes. Seriously. There are boxes with the name light blonde, which portray a brown-haired woman and colour your hair red. What the hell is up with that stuff?
According to wikipedia, you silly non-metrics use the terms large calorie, dietary calorie or food calorie as well. http://en.wikipedia.org/wiki/Calorie
