CUP

unit of volume in the British Imperial and U.S. Customary systems of measurement. The U.S. unit for liquid measurement is different from that for dry measurement. The U.S. liquid cup, which is used much more commonly than is the dry cup, is equal to 14 7/16 cubic inches, or 236.59 cubic cm. The dry cup is equal to 1.164 liquid cups. In Great Britain the single cup, used for both types of measurement, is equal to 1.201 American liquid cups (284.14 cubic cm). In either system a cup is made up of two gills, and two cups make up a pint.
