US Gallons to Quarts

US Gallon

A US gallon (gal) is a common unit of volume used mainly in the United States for measuring liquids such as fuel, milk, and other beverages. One US gallon equals 4 quarts, 8 pints, or 128 fluid ounces, making it a practical size for everyday containers and large-scale liquid purchases. It’s widely recognized at gas stations and in grocery stores, where gallon jugs are frequently sold.

Because the US gallon differs from the Imperial gallon used in the UK, conversions can get confusing across countries. An online converter helps accurately translate gallons into liters or other units for travel, shopping, or cooking with international recipes.

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.
