US Quart vs Millilitre: which is bigger?
A us quart is the larger unit: one us quart equals 946.3529 millilitres. Put another way, you need 946.3529 millilitres to make a single us quart.
What is a US Quart? History, origin and usage
The US quart is literally a quarter of a US gallon, its name coming from the Latin quartus, a fourth, and it therefore traces back to the same Queen Anne wine gallon the United States adopted. Like the gallon, it preserves the pre-1824 English standard that Britain later abandoned.
The US liquid quart is common for dairy, motor oil, sports drinks and small containers of berries or produce in American shops. Recipes and automotive fluids are frequently specified in quarts.
The United States keeps two different quarts: a liquid quart and a slightly larger dry quart used for produce, a distinction that does not exist in the metric world. Both are smaller than the single imperial quart used in the UK.
What is a Millilitre? History, origin and usage
The millilitre is the litre scaled by the metric prefix milli- (Latin mille, a thousandth), so it inherits the litre's origin in the 1795 French metric reforms. Because the litre was defined in relation to the metre, the millilitre became exactly one cubic centimetre when the litre was tied to the cubic decimetre. It has been part of the coherent metric vocabulary ever since the SI prefixes were standardised.
The millilitre is the workhorse small-volume unit almost everywhere outside the United States: medicine doses, syringes and IV bags, drink and food nutrition labels, perfume and cosmetics, and home cooking. Laboratories and pharmacies use it constantly for measuring liquids. In medicine the equivalent term cubic centimetre (cc) is still heard, especially for syringes.
One millilitre is identical in volume to one cubic centimetre, because a litre is exactly one cubic decimetre. A standard metric teaspoon is taken as five millilitres, which is why liquid-medicine dosing cups are graduated in millilitres rather than spoons.

Tips for converting US Quart to Millilitre
- To go from us quart to millilitre, multiply by 946.3529; to go back, divide by 946.3529 (or multiply by 0.001056688).
- For a quick mental estimate, remember that 1 us quart ≈ 946.3529 millilitre, so 10 us quart ≈ 9,463.529 millilitre.
- The converter above keeps full precision; the tables round for readability, so use the tool for exact figures.
- Both fields update live as you type — change either side to convert in that direction.
How to use this US Quart to Millilitre converter
Type a number into the US Quart field and the equivalent in Millilitre appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Millilitre field to convert the other way (millilitre to us quart). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 US qt = 946.3529 mL), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for us quart-to-millilitre conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Sources
- NIST Special Publication 811 — Guide for the Use of the SI — publishes the exact metric equivalents of the customary units. The inch, foot, yard and mile are defined exactly in metres by the 1959 international yard-and-pound agreement, so every imperial figure on this page is exact, not rounded.
- BIPM — The International System of Units (SI Brochure) — the defining document for the SI, published by the International Bureau of Weights and Measures. It fixes the base unit that this conversion resolves to, which is why the factor here can be exact rather than approximate.
Watch the system: a <strong>US</strong> gallon, quart, pint and fluid ounce are <strong>not</strong> the same size as the <strong>imperial (UK)</strong> ones — a US gallon is 3.785 L while an imperial gallon is 4.546 L, and a US fluid ounce (29.57 mL) is slightly larger than an imperial fluid ounce (28.41 mL). The units on this page are labelled US or Imperial so the result is unambiguous.
