Quarts to Liters Converter
Convert US quarts (qt) to liters (L)
Quart (US)
Definition: The US liquid quart (symbol: qt) is a unit of volume used primarily for measuring liquids. One US quart equals exactly 0.946352946 liters or 946.353 milliliters. There are 2 pints in 1 quart, 4 quarts in 1 gallon, and 4 cups in 1 quart.
History/origin: The quart derives from the Latin "quartus," meaning "a fourth," as it represents one-quarter of a gallon. The US liquid quart was standardized as 1/4 of a US gallon (946.353 mL). The US quart differs from the imperial quart (used in the UK), which is larger at 1.136 liters. There's also a US dry quart (1.101 L) used for measuring dry goods, though the liquid quart is more commonly used.
Current use: The US quart is commonly used in the United States for measuring liquids, particularly beverages, milk, soup, and other liquid foods. Quarts are standard in grocery stores for packaging milk, juice, and ice cream. The quart sits between the pint (smaller) and gallon (larger) in the US customary system. Converting quarts to liters is essential when purchasing beverages internationally, following international recipes, or understanding metric volume specifications.
Liter
Definition: The liter (symbol: L or l) is a unit of volume in the metric system. One liter is equal to 1,000 milliliters or 1 cubic decimeter (dm³). The liter is a derived unit accepted for use with the International System of Units (SI).
History/origin: The liter was introduced in France in 1795 as part of the new metric system. Originally defined as the volume of one kilogram of pure water at maximum density, it was later redefined in 1964 as exactly one cubic decimeter. The name "liter" comes from the French "litre," which was derived from an older French unit called the "litron."
Current use: The liter is the standard unit for liquid volume measurements worldwide, except in the United States. It's used extensively for beverages (soft drinks, water, juice), fuel (gasoline, diesel), and liquid products. Liters appear on virtually all beverage bottles and containers globally. Converting quarts to liters is essential when traveling internationally, using metric recipes, or purchasing products that use metric measurements.

How to Convert Quarts to Liters
Formula:
1 qt = 0.946352946 L (exact)
1 L = 1.056688 qt
L = qt × 0.946352946
Quick Mental Math:
Multiply qt by 0.95 to get approximate liters
For quick estimates, you can use 1 qt ≈ 0.95 L or simply 1 qt ≈ 1 L (within 5%)
Common Approximations:
1 qt ≈ 0.95 L (very close approximation)
2 qt ≈ 1.9 L (about 2 liters)
4 qt ≈ 3.8 L (1 gallon)
1 qt ≈ 950 mL
Useful Relationships:
1 quart = 0.946 L = 946.353 mL = 2 pints = 4 cups
1 gallon = 4 qt = 3.785 L
1 pint = 0.5 qt = 0.473 L
1 liter = 1,000 mL = 1.057 qt
Examples:
Convert 1 quart to liters:
1 qt × 0.946352946 = 0.946 L
This is approximately 0.95 liters (very common measurement)
Convert 2 quarts to liters:
2 qt × 0.946352946 = 1.893 L
This is about 1.9 liters (half a gallon)
Convert 4 quarts to liters:
4 qt × 0.946352946 = 3.785 L
This is about 3.8 liters (1 gallon)
Convert 3 quarts to liters:
3 qt × 0.946352946 = 2.839 L
This is about 2.8 liters
Convert 0.5 quarts to liters:
0.5 qt × 0.946352946 = 0.473 L
This is about 473 mL (1 pint)
