Gallon (US)

Definition:In both the US customary and imperial systems of measurement, a gallon is a unit of volume specifically for liquid capacity. 231 cubic inches are regarded as one US gallon (3.785 liters). The imperial gallon, on the other hand, is defined as 4.54609 liters and is used in the UK, Canada, and several Caribbean countries. The gallon is divided into four quarts in both systems. After that, quarts are split into two pints, and pints are split into two cups. One gallon equals four quarts, eight pints, sixteen cups, or thirty-two gills because a cup is made up of two gills. The US gallon and the imperial gallon are further distinguished by the fact that the former is divided into four fluid ounces and the latter into five.A US fluid ounce is therefore 1/128 of a US gallon while an imperial fluid ounce is 1/160 of an imperial gallon.
