How to Convert Quarts to Milliliters
To convert quarts to milliliters, multiply the volume by the following conversion ratio: 946.352946 milliliters/quart.
Since one quart is equal to 946.352946 milliliters, you can use this simple formula to convert:
The volume in milliliters is equal to the volume in quarts multiplied by 946.352946.
For example, here's how to convert 1 quarts to milliliters using the formula above.
How Many Milliliters Are in a Quart?
There are 946.352946 milliliters in a quart, which is why we use this value in the formula above.
Our quart to milliliter calculator automatically converts your volume measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Quarts and milliliters 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 Milliliter?
A milliliter is a unit of volume equal to 1/1,000 of a liter (0.001 L). One-thousandth of a liter, identical to 1 cubic centimeter (cc). [2]
The milliliter is classified as a metric and SI-compatible unit of volume. Milliliters can be abbreviated as mL; for example, 1 milliliter can be written as 1 mL.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the milliliter (mL) a convenient decimal multiple of the liter (L).
In practice, milliliters (mL) are widely used across fine-tolerance laboratory, analytical, and micro-scale volume measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting volume between quarts (qt) and milliliters (mL), keep full floating-point precision (1 qt = 946.352946 mL; 1 mL = 0.0010567 qt) during intermediate calculations and round only the final milliliter figure to match your instrument tolerance.
