I was amused to see (kilo)grams used for the weights. I'll admit that as an American, I have no idea what my weight is in kilograms. Body weight is something that I always think of in pounds. I do use grams sometimes in food prep, but I think even that makes me a bit of an abnormality around here.
Not that I am complaining about their unit choice. I think American's would do well to be a bit more "bilingual" in our measurement systems. Also, the measurements they give are a lot easier to parse than 3/128 oz per 1lb bodyweight.
