About Milliliter to US Quart Conversion

Converting milliliter to us quart comes up frequently in cooking, chemistry, medicine, and engineering. A recipe written in metric units may need to be adapted for a kitchen using us quart, or a laboratory protocol may specify volumes in milliliter that need to be measured with equipment calibrated in us quart.

In everyday use, knowing that 5 mL = 0.005283 qt and 10 mL = 0.01057 qt covers most common situations. For bulk calculations, 100 mL = 0.1057 qt is a useful anchor. The reverse conversion — us quart back to milliliter — uses the factor 946.4, so 1 qt = 946.4 mL.

All conversions use the internationally recognized factor of exactly 1 mL = 0.001057 qt. Calculations are performed in IEEE 754 double-precision floating point, giving accuracy to at least 8 significant figures — more than sufficient for any practical application.

Quick Answer

Formula: US Quart = Milliliter × 0.0010566881

Multiply any milliliter value by 0.0010566881 to get us quart. One milliliter equals 0.0010566881 qt.

Reverse: Milliliter = US Quart × 946.353

Worked Examples

One US quart
946 mL × 0.0010566881 = 0.99962699 qt
946 mL = 1 US quart — motor oil bottle size.
One US pint
473 mL × 0.0010566881 = 0.49981349 qt
473 mL = 0.5 quarts = 1 US pint.
One US cup
237 mL × 0.0010566881 = 0.25043509 qt
237 mL = 0.25 quarts = 1 US cup.
One US gallon
3785 mL × 0.0010566881 = 3.9995646 qt
3,785 mL = 4 quarts = 1 US gallon.

Frequently Asked Questions

About Milliliter and US Quart

Milliliter (mL)

The milliliter is one-thousandth of a liter, in use since the metric system was codified in France in 1795. The milli- prefix (from Latin mille, thousand) was standardized as part of the original SI prefix system.

Milliliters are the workhorse of medicine and cooking: syringes, dropper bottles, and nutritional labels all rely on mL for precise small-volume measurement. A standard US teaspoon is approximately 4.929 mL.

Interesting fact: The milliliter is numerically identical to the cubic centimeter (cm³), so 1 mL = 1 cm³ exactly. This equivalence is widely used in medicine, where a 5 cc syringe holds exactly 5 mL.

US Quart (qt)

The US liquid quart is one-quarter of a US gallon, equal to 946.353 mL. The word 'quart' comes from Old French quarte (fourth part), dating to medieval England.

Quarts are standard in American cooking and food packaging: motor oil, paint, cream, and ice cream are commonly sold in quart containers.

Interesting fact: The US quart and the Imperial quart differ significantly — the Imperial quart is 1.136 liters versus 0.946 liters for the US quart.
