How to convert quarts to gallons
gallons = quarts ÷ 4
Example: 3 qt ÷ 4 = 0.75 gal.
Divide the quarts by 4. 6 quarts are 1.5 gallons, 10 quarts are 2.5 gallons, and 14 quarts are 3.5 gallons.
Odd totals are easiest as whole gallons plus leftover quarts. 11 quarts make two gallons and three quarts, or 2.75 gallons as a decimal. The leftover quarts tell you exactly how full the last jug will be.
If your recipe lists cups rather than quarts, divide the cups by 16 to go straight to gallons. Going from gallons back to quarts is a multiplication by 4, and the gallons to quarts page has its own chart.
US vs UK quarts and gallons
The count is the same in Britain, where 4 imperial quarts make an imperial gallon. Only the sizes differ: the imperial quart and gallon are each larger than their American namesakes by the same factor, 1.201.
Swap one system for the other and the fraction breaks. An imperial quart is 0.3002 of a US gallon rather than an exact quarter, and a US gallon fills only 0.8327 of an imperial gallon. For metric comparisons, the quarts to liters converter is the neutral ground.
| Unit | Size | Used in |
|---|---|---|
| US quart | 946.4 ml | US |
| imperial quart | 1,137 ml | UK |
| US gallon | 3,785 ml | US |
| imperial gallon | 4,546 ml | UK |
Will your batch fit in a gallon container?
When you mix by the quart but store in a container sized in gallons, divide by 4 before you pour. A brine of 9 quarts comes to 2.25 gallons, so it needs a container larger than 2 gallons.
Leave room for whatever goes into the liquid. A turkey or a load of vegetables pushes the level up, so choose a bucket or cooler with plenty of space above the brine line.
Quarts and gallons: questions
Is 2 quarts half a gallon?
Yes, 2 quarts equal 0.5 gallon, which is why a half-gallon carton holds the same as two quart cartons. Both come to 8 cups, or 64 fluid ounces. Either one fills a pitcher sized for half a gallon.
How many gallons are 8 quarts?
8 quarts make exactly 2 gallons. A stockpot rated at 8 quarts is therefore a two-gallon pot, which is worth knowing when a recipe gives its volume in gallons. Filled to the brim, it holds 32 cups.
How many gallons is 5 quarts?
5 quarts are 1.25 gallons: one full gallon plus one quart. If you have only gallon jugs, you need two of them, and the second will be a quarter full.
How many gallons are 20 quarts?
20 quarts make 5 gallons, or 80 cups. At that size, counting in gallons is far easier: think of five groups of four quarts rather than twenty separate ones. In fluid ounces, the total is 640.
Is a quart a quarter of a gallon?
Yes, and the names hint at it. One US quart is 0.25 gallon, or 32 fluid ounces out of the gallon's 128 fluid ounces. The same holds for British units, as long as the quart and gallon are both imperial.
