Quarts to UK Gallons

Quart

A quart (qt) is a US customary unit of volume commonly used for measuring liquids like milk, juice, and cooking ingredients. One quart equals 4 cups, 2 pints, or 32 fluid ounces, making it a convenient size for everyday food and beverage containers. The word comes from “quarter,” representing one-quarter of a US gallon.

Quarts can be confusing in international contexts because the US and UK (Imperial) systems define the quart differently. A conversion tool helps ensure correct results when switching between quarts, liters, gallons, and other units used around the world.

UK Gallon (Imperial Gallon)

A UK gallon, also called an Imperial gallon, is a volume unit used primarily in the United Kingdom and some Commonwealth countries. It is larger than the US gallon, holding the equivalent of 4 quarts, 8 pints, or 160 fluid ounces. The Imperial gallon is still commonly used to measure fuel at petrol stations and in older beverage packaging.

Because the UK gallon is different from the US gallon, international conversions can be misleading if the type of gallon isn’t specified. Using a volume converter ensures accurate translation to liters, cups, or other measurement systems when comparing product sizes from different countries.
