Gallon (gal) Conversions
The gallon is a unit of measurement for volume and fluid capacity in both the US customary units and the British imperial systems of measurement. There are four quarts in a gallon and eight pints in a gallon, and they have different sizes in different systems.
The US liquid gallon is legally defined as 231 cubic inches, which is exactly 3.785411784 litres. A US liquid gallon of water weighs about 8.34 pounds or 3.78 kilograms at 62 °F (17 °C), making it about 16.6% lighter than the imperial gallon. There are four quarts in a gallon, two pints in a quart and 16 US fluid ounces in a US pint.
