US, metric and Australian cups

Australia, New Zealand and Canada use a 250 ml metric cup, about 6% bigger than the US cup. For most recipes that's fine as long as you use the same cup for everything. Australian tablespoons are different, though: they hold 20 ml, not 15 ml, so use 3 teaspoons for each US tablespoon. Nutrition labels in the US use a rounded 240 ml cup.
