How to Convert Quarts to Liters (Formula + Examples)

To convert quarts to liters, multiply by 0.946353 — one US liquid quart equals 0.946 liters, so 4 quarts make 3.785 liters (one gallon). For liters to quarts, multiply by 1.05669 instead. Convert either direction instantly with our free quarts to liters converter.

The Formula: Multiply by 0.946353

The quarts to liters formula is one step: liters = quarts × 0.946353. Two quarts of stock is 1.893 liters. Six quarts of paint is 5.678 liters. Half a quart of milk is 0.473 liters — which is also a pint, since two pints make a quart. The factor is exact enough for every real purpose; the full constant is 0.946352946 liters per US liquid quart, and rounding to 0.946 costs you less than a milliliter per quart. Sanity check every answer the same way: a quart is just under a liter, so your answer in liters should always be slightly smaller than the number of quarts you started with. If it comes out bigger, you multiplied by the wrong factor — the classic mistake, covered below. For one-click answers, our quarts to liters converter runs the formula both directions.

How Many Liters in a Quart?

How many liters in a quart? 0.946 liters — just under a liter. This is the anchor value worth memorizing, because everything else in the quart family hangs off it: 2 quarts is 1.893 L (a half gallon), 4 quarts is 3.785 L (a gallon), 8 quarts is 7.571 L (two gallons). The quart sits at the exact midpoint of the US liquid ladder — cup (0.237 L), pint (0.473 L), quart (0.946 L), half gallon (1.893 L), gallon (3.785 L) — each step doubling the last. That doubling is the mental-math shortcut: if you know a quart is ~0.95 L, a pint is half that (~0.47 L) and a half gallon is double (~1.9 L). Cooks use this constantly: a recipe calling for 2 quarts of broth is asking for just under 2 liters, and a 1-quart saucepan holds just under a liter of soup. For the full jug-scale picture, see our guide to how many liters are in a gallon of milk, which walks the whole ladder from cup to gallon.

Worked Examples: Real Kitchen and Workshop Numbers

Example 1 — a soup recipe calls for 3 quarts of stock: 3 × 0.946353 = 2.839 liters. Example 2 — a paint can holds 2.5 quarts: 2.5 × 0.946353 = 2.366 liters. Example 3 — an engine takes 5 quarts of oil: 5 × 0.946353 = 4.732 liters — which is why 5-quart oil jugs are sold as 4.73 L in metric countries. Example 4 — a 12-quart cooler: 12 × 0.946353 = 11.356 liters. Notice how the answers cluster near the input number, always slightly below it — that is your built-in error detector. If you ever get 3 quarts = 3.17 liters, you used the reverse factor (that is quarts from liters). Keep the direction straight with the mnemonic: “quarts to liters shrinks” (0.946 < 1), “liters to quarts grows” (1.057 > 1).

The Reverse: Liters to Quarts (Multiply by 1.05669)

Going the other direction, the liters to quarts formula is quarts = liters × 1.05669. Two liters of soda is 2.113 quarts — just over two quart bottles, which is why the 2-liter bottle replaced the quart in the soda aisle decades ago. Five liters of water is 5.283 quarts. Ten liters — a standard bucket — is 10.567 quarts. The reverse factor is simply 1 ÷ 0.946353, so the two formulas are exact inverses; converting there and back returns your starting number (2 qt → 1.893 L → 2.000 qt), which makes a nice round-trip check on any calculator. When a European recipe lists liters and your measuring pitchers are marked in quarts, run it through our quarts to liters converter in reverse — or bookmark our liters to gallons converter for the bigger jug sizes, since most bulk conversions land on gallons anyway.

US Quart vs Imperial Quart: The 20% Trap

Here is the trap: the US liquid quart (0.946 L) and the imperial quart (1.13652 L) differ by a full 20%. The imperial quart is one quarter of the imperial gallon (4.546 L ÷ 4), while the US quart is one quarter of the US gallon (3.785 L ÷ 4) — same fraction, different gallon, different quart. In practice, American recipes, American measuring cups, and American product labels always mean the US quart, so 0.946 is your default. The imperial quart only appears in older British recipes and Commonwealth product specs. If a conversion ever looks 20% off from what you expect, check which quart the source meant before doubting your math. Our US vs UK gallon guide traces the full history of the split — the quart inherited the whole mess, a quarter at a time.

Liquid Quart vs Dry Quart: A Second Trap

There is a second, rarer quart: the US dry quart, equal to 1.101 liters. Dry quarts measure produce and grain — berries, tomatoes, oats — and show up on farmers’ market containers and seed packets. The dry quart is about 16% larger than the liquid quart because it derives from the bushel system rather than the gallon system. For cooking and all liquid conversions, ignore it completely: recipes, bottles, and pitchers always mean liquid quarts. But if you are converting a produce box labeled “1 dry quart of strawberries,” that is 1.101 L of berries, not 0.946 — and no, you cannot neatly convert it to a weight, because a quart of strawberries and a quart of blueberries weigh different amounts. When in doubt, “quart” alone means liquid; “dry quart” says so explicitly.

Quarts to Liters in Excel

For a column of values, Excel needs one formula: if quarts are in column A, put =A2*0.946353 in B2 and fill down. For the reverse direction, =A2*1.05669. Two refinements: wrap in ROUND for clean output (=ROUND(A2*0.946353,2) gives 2.84 instead of 2.83906), and label the columns explicitly (“Quarts (US liquid)” and “Liters”) so nobody later “repairs” your sheet by converting it again. If the sheet mixes US and imperial quarts, add a helper column for the system and use =IF(C2=“imp”,A2*1.13652,A2*0.946353). For fluid-ounce columns in the same workbook, our fluid ounces to liters converter covers the 29.5735 ml factor the same one-formula way — and our ounces to liters formula guide walks through the method step by step.

Quarts to Liters: Quick Chart

The values people look up most: 1 quart = 0.946 L. 2 quarts = 1.893 L (a half gallon). 3 quarts = 2.839 L. 4 quarts = 3.785 L (a gallon). 5 quarts = 4.732 L. 6 quarts = 5.678 L. 8 quarts = 7.571 L (two gallons). 10 quarts = 9.464 L. 12 quarts = 11.356 L. Reverse anchors: 1 liter = 1.057 quarts; 2 liters = 2.113 quarts; 5 liters = 5.283 quarts. For anything off the chart, the ×0.946 rule beats scrolling — 7 quarts is 7 × 0.946 = 6.62 L, and you can check it against the 8-quart row (7.57 L) to confirm it lands sensibly below.
