Liter to Quart Converter
What Is a Liter?
The liter (L) is a metric unit of volume equal to 1,000 milliliters or 1 cubic decimeter. It is the global standard for liquid volume in cooking, commerce, automotive, and science. Most countries outside the US use liters for everyday liquid measurements.
What Is a Quart?
The US liquid quart (qt) is a customary unit of volume equal to 2 pints, 4 cups, or 32 fluid ounces (946.353 mL). It is used in the United States for milk, juice, cooking, and automotive fluids (oil, coolant). Note: the UK imperial quart is larger (1,136.5 mL) — this converter uses the US liquid quart.
Liters to Quarts Formula
The conversion factor is:
US quarts = liters × 1.05669
Derived from: 1 US qt = 946.353 mL, so 1 L = 1,000 / 946.353 ≈ 1.05669 qt.
Worked Example
Convert 4 liters of engine oil to US quarts:
- Multiply: 4 × 1.05669 = 4.227 quarts
So 4 liters ≈ 4.23 quarts — slightly more than 4 quarts (1 gallon). This is why a "4-liter" oil change requires buying 5 quarts.
Quick Estimation
A liter is almost the same as a quart — just 5.7% bigger. For everyday purposes, 1 L ≈ 1 qt is close enough. For precision: add 6% to the liter value. Example: 3 L + 6% = 3.18 qt (exact: 3.17 qt).

Which Is Bigger: Liter or Quart?
A liter is 5.7% bigger than a US quart. One liter = 1,000 mL, while one US quart = 946 mL. The difference is small — about 54 mL (less than a quarter cup). For rough estimates, treat them as equal.
When You Need This Conversion
- Cooking: European recipes in liters; US recipes in quarts. 1 liter of broth ≈ 1 quart — close enough for most recipes.
- Automotive: Engine oil in the US is sold in quarts (4-5 qt change). European manuals specify liters. 5 liters = 5.28 quarts.
- Beverages: A 2-liter soda = 2.11 quarts. A US gallon (4 quarts) = 3.785 liters.
Frequently Asked Questions
How many quarts are in a liter?
1 liter = 1.05669 US quarts. A liter is about 5.7% larger than a US quart. For rough estimates, they are nearly interchangeable.
Is a liter bigger than a quart?
Yes — a liter (1,000 mL) is about 5.7% bigger than a US quart (946 mL). The difference is about 54 mL, less than a quarter cup.
How many liters is a gallon?
1 US gallon = 4 quarts = 3.785 liters. So a gallon is about 3.8 liters. A common shortcut: 1 gallon ≈ 4 liters (overshoots by 5.7%).
What is the difference between a US quart and a UK quart?
A US liquid quart = 946 mL. A UK (imperial) quart = 1,137 mL — about 20% larger. This converter uses the US quart. Always check which system a recipe uses.
How many quarts of oil is 5 liters?
5 liters = 5.28 quarts. Since oil is sold in whole-quart containers in the US, you would need 6 quarts (with some left over) for a 5-liter oil change.
