Cup (Imperial): is a unit of volume used in the imperial system, which was historically used in the United Kingdom and its former colonies. Though it has been largely replaced by the metric system in most of these countries, the imperial cup is still recognized and sometimes appears in older recipes and documents.
1 imperial cup = 284.131 milliliters (mL), which makes it larger than both the U.S. customary cup (236.588 mL) and the metric cup (250 mL). Quart (US liquid): unit of volume in the U.S. customary system, commonly used to measure liquids. The name "quart" comes from the Latin word quartus, meaning "fourth," as a quart is traditionally one-fourth of a gallon.
The U.S. liquid quart is abbreviated as "qt" and 1 U.S. liquid quart is 32 U.S. fluid ounces which is 946.352946 milliliters.
