SponsoredThis calculator converts a volume in quarts to US gallons using the exact ratio: divide the quart value by 4. One US quart is defined as exactly one quarter of a gallon, and one gallon as exactly 3,785.411784 mL, so this conversion carries no rounding at all.
Recipes, canning instructions, and bulk liquid purchases often build up a total in quarts, and converting back to gallons makes it easier to compare against a gallon-sized container or a store's gallon pricing. This comes up constantly when scaling a recipe or stocking up on a liquid sold by the gallon.
For the reverse direction, converting gallons back into quarts, or converting a quart value into cups instead, see the related converters below.

The Quarts to Gallons Formula
To convert quarts to gallons, divide the quart value by 4. For example, 10 quarts divided by 4 equals 2.5 gallons.
To go the other way, use the Gallons to Quarts converter instead, which multiplies by 4 for you. For the smaller cup scale instead, see the Quarts to Cups converter below.
Why 4 Quarts Make a Gallon
A US gallon holds exactly 4 quarts, a ratio fixed by the legal definition of both units. This is specifically the US customary gallon and quart, the units used on US containers and recipes.
Converting an Odd Quart Count
Not every quart total converts to a clean fraction of a gallon. 3 quarts, for example, equals 0.75 gallon, easy enough, but a running total like 5 quarts equals 1.25 gallons, a genuinely awkward figure many people round to "about a gallon and a quart" in casual conversation instead.
To find what a volume weighs, the Quarts to Pounds Converter converts quarts to pounds for water, milk, flour, sugar, honey, or butter. The Gallons to Pounds Converter does the same starting from gallons. To double a recipe or cut it down first, the Recipe Scaling Calculator adjusts any ingredient amount for a new number of servings.

No. A volume can't be below zero, so a negative entry shows a dash instead of a result. A minus sign in front of a value is usually a typing slip.
