Fluid ounces to UK Gallons

Fluid Ounce

A fluid ounce (fl oz) is a common US customary unit of volume used to measure liquids such as beverages, cooking ingredients, and personal care products. One US fluid ounce equals 1/8 of a cup or about 29.57 milliliters. You’ll often find this unit printed on drink bottles, medicine labels, and kitchen tools where precise small measurements are needed.

Because the fluid ounce is commonly used in the United States while many other countries rely on the metric system, converting fluid ounces to milliliters, cups, or liters is a frequent need. A converter helps provide quick, accurate results that make cooking and product comparisons easier.

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.
