Liters to Quarts Converter

Convert liters to quarts with our free liters to quarts converter — or flip it and turn quarts back into liters. One liter is just over a quart, so the two units are close cousins, and this tool converts either way in seconds, with no sign-up and no download. It also converts milliliters, US gallons, cups, pints, and fluid ounces, plus imperial quarts and gallons.

How it works

The liter is the metric unit of volume, used almost everywhere in the world for drinks, fuel, and cooking. The quart is the customary unit used in the United States: four quarts make a gallon, two pints make a quart, and a quart is the size of a large measuring jug. Because the two systems meet constantly — in recipes, on drink bottles, and at the fuel pump when traveling — converting between them is an everyday job.

The exact relationship is simple: 1 liter equals 1.05669 US quarts, and 1 US quart equals 0.946353 liters. To turn liters into quarts, multiply by 1.05669. To turn quarts into liters, multiply by 0.946353 — or divide by 1.05669, which gives the same answer. The converter above does the math for you and also shows gallons, since four quarts make a gallon and many people think in gallons for larger amounts.

For everyday use, a rough rule works well: a liter is about 6 percent more than a quart, so the two are nearly interchangeable when precision does not matter. A 2-liter bottle of soda is about 2.11 quarts, and a 1-quart carton of milk is about 0.95 liters. For baking and for engine oil, where the exact amount matters, use the precise factor rather than the rough rule — the converter shows five decimal places so the result is exact enough for any recipe or refill.

Watch out for one trap: the UK imperial quart is bigger than the US quart. A UK quart is 1.13652 liters, while a US quart is 0.946353 liters — a difference of about 20 percent. This converter uses the US liquid quart, the one marked on measuring jugs, milk cartons, and motor oil bottles in the United States. A recipe from a British cookbook that calls for quarts is using the larger imperial quart, so convert with that in mind.

Common uses include scaling a recipe written in liters for a kitchen that measures in quarts, working out how much oil a car needs when the manual lists liters, comparing drink bottle sizes while shopping, and converting a fuel amount when traveling between countries that sell fuel by the liter and by the gallon.

Worked example

David is making soup from a recipe that calls for 1 liter of stock, but his measuring jug is marked in quarts. He wants to know how many quarts to pour.

Step 1: Write down the amount in liters — 1 liter.
Step 2: Use the conversion factor — 1 liter = 1.05669 US quarts.
Step 3: Multiply: 1 × 1.05669 = 1.05669.
Step 4: Read the result — 1.05669 US quarts, or just over one quart.

The reverse direction works the same way. One US quart is 1 × 0.946353 = 0.946353 liters, so a 1-quart carton holds just under a liter. And four quarts make a gallon: 4 × 0.946353 = 3.78541 liters per gallon. Those are the exact results this converter gives for 1 liter and for 1 quart, and they are the numbers David can use to measure his stock without guessing.
