How to convert gallons to quarts
quarts = gallons × 4
Example: 2 gal × 4 = 8 qt.
Multiply the gallons by 4. The names make it easy to remember, since a quart is a quarter of a gallon.
A gallon and a half is 6 quarts, and 2.5 gallons make 10 quarts. Three quarters of a gallon works out to 3 quarts, and a gallon and a quarter to 5 quarts.
If your jug is marked in cups rather than quarts, go one step further. Each quart holds 4 cups, so 2.5 gallons are also 40 cups. To turn quarts back into gallons, divide by the same factor, as the quarts to gallons page shows.
US vs UK gallons and quarts
Both systems split the gallon into quarters, but the gallons themselves differ. NIST Handbook 44 defines the US gallon as 231 cubic inches, while the imperial gallon is exactly 4.54609 liters (litres).
Because the imperial gallon is 1.201 times as large, each imperial quart is larger by the same factor. A US gallon therefore holds only 3.331 imperial quarts. Keep the gallon and the quarts from the same system and the rule stays exact.
| Unit | Size | Used in |
|---|---|---|
| US gallon | 3,785 ml | US |
| imperial gallon | 4,546 ml | UK |
| US quart | 946.4 ml | US |
| imperial quart | 1,137 ml | UK |
Splitting a gallon into quart containers
Big batches of stock, soup or iced tea are easier to store in quarts. A stockpot that yields 3 gallons fills 12 quart containers, and every extra gallon adds 4 more.
If the containers go into the freezer, stop short of the rim so the liquid has room to expand. That leaves a little over, so have one spare container ready. For smaller portions, the same batch fills twice as many pint containers, since each quart holds 2 pints.
Gallons and quarts: questions
How many quarts are in half a gallon?
Half a gallon is 2 quarts. A half-gallon carton of milk or juice holds exactly that, so two quart cartons give you the same amount. Either one covers a recipe that asks for 8 cups of liquid.
Which is bigger, a quart or a gallon?
The gallon is bigger. It holds 4 quarts, so one quart is only 0.25 gallon. Measured with a cup, the quart holds 4 cups and the gallon 16 cups, which is why a quart carton looks so small next to a gallon jug.
How many quarts are in 5 gallons?
5 gallons equal 20 quarts, or 80 cups. For numbers that size, think of every gallon as a group of 4 quarts and count the groups. A bucket that holds 5 gallons would fill that many quart jars.
How many quarts are in an imperial gallon?
An imperial gallon holds 4 imperial quarts of 1,137 ml each. Measured in US quarts, the same gallon is 4.804, because each US quart is smaller at 946 ml. A British recipe that calls for a gallon therefore needs almost five US quart cartons.
Is a quart the same as a liter?
No, but they are close. A US quart is 0.946 L, a little under a liter, while an imperial quart is 1.137 L, a little over. For exact metric amounts, use the gallons to liters converter.
