Cup

A cup is a unit of volume measurement of volume equal to 16 tablespoons, 1/2 pint, 1/4 quart, or 8 fluid ounces.

A cup is about 237 ML. Rougher equivalents are 240 ML and 250 ML, where the latter fits nicely with a pint of 500 ML and a pound of 500 g.

A metric cup is 250 ML in Australia, Canada, New Zealand and the UK. These countries previously used the imperial system, in which a cup would be 284 ML or 6/5 US cups.
