Ans. In the US customary system and the British Imperial System, a gallon is a unit of measurement both for volume and fluid capacity. A gallon is larger than a pint, quart, and cup. Both the US liquid and imperial gallon split into four quarts (also known as quarter gallons), which further splits into two pints, which in turn splits into two cups. Thus, we can say gallons are equal to four quarts, eight pints, and sixteen cups.
