Liters to Quarts Converter

How to use the liters to quarts converter

1. Enter a value in the Liters field to convert to quarts, or enter a value in the Quarts field to convert to liters.
2. The result updates automatically as you type.
3. Use the output rows to see the converted value along with related volume equivalents.

How the conversion works

The relationship between liters and US liquid quarts is defined by an exact factor established by NIST. One US liquid quart equals exactly 0.946352946 liters. Therefore, to convert liters to quarts, you divide by that number, which is the same as multiplying by its reciprocal:

quarts = liters / 0.946352946

For example, converting 3 liters to quarts: 3 / 0.946352946 = 3.170065 qt. To go from quarts to liters, multiply instead: liters = quarts * 0.946352946. The spelling "litres to quarts" uses the international English form, but the math is identical. Because the factor is derived from the exact definition of the US gallon (231 cubic inches) and the inch (exactly 2.54 centimeters), there is no rounding error in the constant itself. Any imprecision comes only from how many decimal places you choose to display.

Common conversions reference table

This table lists frequently needed values when converting liters to quarts and quarts to liters. All figures are rounded to six decimal places for precision.

Keep this table handy when scaling recipes up or down. If you need intermediate values, simply multiply the liter amount by 1.056688209 to get the quart equivalent.

US liquid quarts versus other quart types

When people search for quarts to liters, they almost always mean the US liquid quart. However, other definitions exist. The US dry quart is about 1.101221 liters, used historically for agricultural goods like berries or grain. The UK imperial quart is larger still, at exactly 1.1365225 liters. Mixing these up leads to errors of up to 20 percent. This tool strictly uses the US liquid quart (0.946352946 L) to match everyday American recipes, automotive fluid capacities, and consumer packaging. If you are working with British recipes, be sure to account for the difference, as an imperial quart holds roughly 20 percent more liquid than its American counterpart.

Practical use cases

Converting liters to quarts comes up often in cooking, automotive maintenance, and science. European recipes list liquids in liters or milliliters, while American kitchens measure in quarts, pints, and cups. If a recipe calls for 1.5 liters of broth, you need about 1.585 quarts. Car owners changing oil might buy a 5-liter jug and need to know it holds roughly 5.28 quarts. For smaller amounts, you can also convert using liters to ml or check pints to quarts since there are two pints in every quart. Laboratory work frequently requires switching between metric and US customary volumes, making a reliable converter essential for accurate measurements.

Relationship to gallons and other units

A US liquid quart is exactly one quarter of a US gallon. Since one US gallon is 3.785411784 liters, dividing by four gives the exact quart value of 0.946352946 liters. If you need to scale up beyond quarts, a liters to gallons converter handles the full gallon directly. A quart also contains four cups or two pints. You can explore those relationships with the quarts to cups or quarts to ounces tools. Understanding this hierarchy makes mental estimation easier: one liter is just slightly more than one quart, so for rough kitchen work you can treat them as nearly equal, adding about five percent extra when going from liters to quarts.
