Please note that, UK, Australia, New Zealand and a few other commonwealth countries use the metric cups (250 mL) today. But if you need the cups to ounces conversion from the old recipes (pre-1970s), then you may still need the use the capacities from the imperial cups to find out how many ounces in "x" cups in the recipes from those countries.

Canada uses metric cups after mid-1970s but before the metric system is adopted the traditional Canadian cup (8 imperial fluid ounces) was used. Because of Canada's strong ties with US, it is necessary to know the differences of cup capacities and convert between US cups (236.6 mL), traditional Canadian cups (227.3 mL) and the metric cups (250 mL).

If you would like to compare the cup capacities in milliliters (mL) please check cups to mL converter page.

How to convert from cups to ounces?
