SponsoredThis calculator converts a volume in quarts to milliliters using the exact US customary factor: multiply the quart value by 946.352946. One US quart is defined as exactly one quarter of a gallon, and one US gallon as exactly 3,785.411784 mL, so this factor carries no rounding at all.
A quart of a liquid ingredient, motor oil, or paint is a common US measurement, and converting it into milliliters makes it possible to compare against a metric-labeled product or follow a metric recipe. This comes up often when a US and an international product need to be compared directly.
For the reverse direction, converting milliliters back into quarts, or converting a quart value into liters instead, see the related converters below.

The Quarts to Milliliters Formula
To convert quarts to milliliters, multiply the quart value by 946.352946. For example, 1.5 quarts times 946.352946 equals approximately 1,419.53 mL.
To go the other way, use the Milliliters to Quarts converter instead, which divides by the same factor for you. For a quart value that needs to become liters, see the Quarts to Liters converter below.
Why a Quart Is Close to, But Not Exactly, a Liter
A US quart (946.352946 mL) is close to but not the same as a liter (1,000 mL), a genuinely common source of confusion since the two are often used interchangeably in casual conversation. A liter is about 5.7% larger than a US quart.
When the Difference Matters
For a single quart or liter, the roughly 53.6 mL difference rarely matters in casual cooking. It compounds at larger volumes, so a recipe or industrial process converted between quarts and liters without the exact factor can drift noticeably over several units.
To find what a volume weighs, the Quarts to Pounds Converter converts quarts to pounds for water, milk, flour, sugar, honey, or butter. Syringes and some medicine cups are marked in cubic centimeters, and the Cubic Centimeters to Milliliters Converter confirms that 1 cc is exactly 1 milliliter. To double a recipe or cut it down first, the Recipe Scaling Calculator adjusts any ingredient amount for a new number of servings.
