Quarts to Liters Converter: Fast and Simple

A US liquid quart is a quarter of a US gallon: 3.785411784 ÷ 4 = 0.946353 liters, the factor this tool multiplies by. Since a quart is defined relative to the US gallon, it inherits the same US/UK split as gallons and pints — a UK quart is 1.136523 liters, about 20% larger.

Worked example

4 quarts (a full US gallon): 4 × 0.946353 = 3.7854 liters, matching the standard US gallon-to-liter figure exactly, since 4 quarts = 1 gallon by definition.

Where quarts appear

Motor oil, milk, and paint are commonly sold in US quarts in North America — a "quart of oil" is 0.946 liters, which is why a European 1-liter oil bottle holds slightly more than a US quart bottle despite looking like the same size container.
