How Big is a Cup?
Cup measurements are often found in recipes, similarly to spoon measurements, with 1 cup flour or 1 cup caster sugar regularly being seen, especially in American recipes. Over time standard US cup measures have come to be used at 1 US cup being the equivalent of a ½ pint (US) (8 US fluid ounces).
In other English speaking countries the Imperial Cup of half an Imperial pint was formerly used in recipes, this has been replaced in Australia, Canada, New Zealand and South Africa with the metric cup of 250ml. The Cup has not been in common use as a standard measure in British recipes in over 50 years.
