How to Convert Quarts to Liters
To convert quarts to liters, multiply the volume by the following conversion ratio: 0.9463529 liters/quart.
Since one quart is equal to 0.9463529 liters, you can use this simple formula to convert:
The volume in liters is equal to the volume in quarts multiplied by 0.9463529.
For example, here's how to convert 5 quarts to liters using the formula above.
How Many Liters Are in a Quart?
There are 0.9463529 liters in a quart, which is why we use this value in the formula above.
Our quart to liter calculator automatically converts your volume measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Quarts and liters are both units used to measure volume. Keep reading to learn more about each unit.
What Is a Quart?
A quart is a unit of volume equal to 0.9463529 liters (L), the base unit for volume. Equal to 1/4 US gallon or 2 US pints (946.35 mL). [1]
The quart is classified as a US customary unit of volume. Quarts can be abbreviated as qt; for example, 1 quart can be written as 1 qt.
When working with quarts (qt) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, quarts (qt) are widely used across standard volume applications within US customary workflows, engineering documentation, and technical data sheets.
What Is a Liter?
Metric unit of volume equal to 1 cubic decimeter (1,000 mL). It serves as a primary reference unit for measuring volume across scientific and practical applications. [2]
The liter is classified as a metric and SI-compatible unit of volume. Liters can be abbreviated as L; for example, 1 liter can be written as 1 L.
As the primary coherent reference unit for volume in this category, all other volume units are mathematically anchored to the liter (L).
In practice, liters (L) are widely used across standard volume applications within SI metric workflows, engineering documentation, and technical data sheets.
When converting volume between quarts (qt) and liters (L), keep full floating-point precision (1 qt = 0.9463529 L; 1 L = 1.0566882 qt) during intermediate calculations and round only the final liter figure to match your instrument tolerance.
