Cup (unit)

Cooking measure of volume

The cup is a cooking measure of volume, commonly associated with cooking and serving sizes. In the US customary system, it is equal to one-half US pint (8.0 US fl oz; 8.3 imp fl oz; 236.6 ml). Because actual drinking cups may differ greatly from the size of this unit, standard measuring cups may be used, with a metric cup commonly being rounded up to 240 millilitres (legal cup), but 250 ml is also used depending on the measuring scale.
