In Australia and New Zealand: we have skim milk, and call 2% milk "Hi-Lo" - sometimes I see it branded "lite milk". Then there's regular milk. It has 4% fat, but you need to read the fine print on the side of the bottle to learn that. I've heard it called "full cream milk", but usually in a cafe setting when ordering coffee.

My brother in the USA had something called half-and-half in his fridge. I think that one was 8%? You guys would know better than I. We don't have whatever it is.
