1 quart equals 946 ml. In US kitchen measurements, 1 quart is also 4 cups, 32 fluid ounces, or 2 pints. For quick measuring, use 946 ml for an exact metric conversion.
How Many Ml In A Quart – Facts To Know: 1 quart is 946 ml. In U.S. kitchen measuring, that same quart equals 4 cups, 2 pints, or 32 fluid ounces. Use 946 ml when converting a U.S. liquid quart for recipes, labels, meal prep, or measuring pitchers.
The key is that this is the U.S. quart used in American recipes, not an imperial quart. For quick scaling, 1/2 quart is 473 ml, because 1 pint equals 473 ml. A full gallon is 4 quarts, so 1 gallon equals 3.79 litres.
The Short Answer, With Numbers
1 US quart equals 946 ml. In kitchen measures, 1 quart also equals 4 cups. Since 1 cup is 237 ml, 4 cups gives the quart figure used here: 946 ml.
| US measure | US equivalent | Metric |
|---|---|---|
| 1 fluid ounce | 2 tablespoons | 30 ml |
| 1/4 cup | 4 tablespoons | 59 ml |
| 1/2 cup | 8 tablespoons | 118 ml |
| 1 cup | 16 tablespoons / 8 fluid ounces | 237 ml |
| 1 pint | 2 cups | 473 ml |
| 1 quart | 4 cups | 946 ml |
| 1 gallon | 16 cups | 3.79 litres |
Quick quart conversions you will actually use
If a recipe calls for 1 quart of stock, milk, water, or juice, measure 946 ml. If your measuring jug is marked in cups, fill to 4 cups.
If you only have a 1-cup measure, use it 4 times. Each cup is 237 ml, so 4 cups is the listed quart amount: 946 ml.
If you only have a pint mark, use 2 pints. Each pint is 473 ml, and 2 pints equals 1 quart, or 946 ml.
If you are scaling down, 1/2 quart is 2 cups. That is the same as 1 pint, or 473 ml.
A 1/4 quart is 1 cup, which is 237 ml. This is often the easiest way to measure a smaller quart fraction without doing extra math.
Worked examples
Example 1: A soup recipe needs 2 quarts of broth. Use 8 cups total. In metric, that is 946 ml + 946 ml, so measure 1,892 ml.
Example 2: You need 3 quarts of water. Since 1 quart is 4 cups, 3 quarts is 12 cups. Using the quart metric figure, that is 2,838 ml.
Example 3: A punch bowl recipe calls for 1 gallon. The table gives 1 gallon as 16 cups. Since 1 quart is 4 cups, 1 gallon equals 4 quarts.
Using the listed metric figures, 1 gallon is 3.79 litres. That matches the kitchen shortcut: 4 quarts is just under 4 litres.
Common measuring edge cases
Do not treat 1 quart as exactly 1 litre when precision matters. The listed quart is 946 ml, while a litre is 1,000 ml, a difference of 54 ml.
That 54 ml gap is close to, but not the same as, a 1/4 cup measure, which is listed as 59 ml. For baking or concentrated mixes, use the actual quart figure.
If a container shows only fluid ounces, use the cup relationship. A quart is 4 cups, and each cup is 8 fluid ounces, so 1 quart is 32 fluid ounces.
If you measure by tablespoons, 1 cup is 16 tablespoons. A quart is 4 cups, so 1 quart equals 64 tablespoons.
For the fastest answer: 1 quart = 946 ml = 4 cups = 2 pints = 32 fluid ounces.
Milliliters In One Quart
1 US liquid quart = 946 ml. That is the kitchen conversion to use for recipes, drink volumes, broth, milk, water, and other liquid ingredients measured in US quarts.
A quart is 4 cups. Since 1 cup is 237 ml, the math is 4 × 237 ml = 948 ml by cup addition. The reference quart value is 946 ml, so use 946 ml per quart when converting directly.
Quick Quart To Milliliter Conversions
| US liquid measure | Milliliters |
|---|---|
| 1/4 quart | 237 ml |
| 1/2 quart | 473 ml |
| 1 quart | 946 ml |
| 2 quarts | 1,892 ml |
| 4 quarts | 3,784 ml |
For everyday cooking, 1 quart is just under 1 liter. A liter is 1,000 ml, while a US quart is 946 ml. The difference is 54 ml, which is a little less than 1/4 cup.
If a soup recipe calls for 2 quarts of stock, use 1,892 ml. If your measuring jug is marked in 500 ml steps, that is 1,500 ml plus 392 ml.
If a sauce recipe calls for 1/2 quart of milk, use 473 ml. That is the same volume as 1 pint, because 1 pint equals 2 cups and 1 quart equals 4 cups.
If a brine calls for 1/4 quart of water, use 237 ml. That is the same as 1 cup. This is useful when scaling a 1-quart formula down to a small batch.
Quart, Cup, Pint, And Gallon Relationships
Use these exact US liquid relationships: 1 quart = 4 cups, 1 pint = 2 cups, and 1 gallon = 16 cups. Therefore, 1 gallon equals 4 quarts.
Since 1 gallon is 3.79 litres, 1 gallon is 3,790 ml. Dividing by 4 gives about 947.5 ml per quart, close to the listed direct quart value of 946 ml.
The small mismatch comes from rounded kitchen reference values. For one ingredient in a home recipe, use the listed quart conversion: 1 quart = 946 ml.
Worked Examples
Example 1: Convert 3 quarts to ml. Multiply 3 × 946 ml. The answer is 2,838 ml.
Example 2: Convert 1 1/2 quarts to ml. Add 946 ml plus 473 ml. The answer is 1,419 ml.
Example 3: Convert 2 1/4 quarts to ml. Add 1,892 ml plus 237 ml. The answer is 2,129 ml.
Example 4: You have a 946 ml carton and need 1/2 quart. Use 473 ml, leaving 473 ml in the carton.
Common Edge Cases
Do not confuse a quart with a cup. One quart is 4 cups, so using 237 ml instead of 946 ml gives only one quarter of the needed liquid.
Do not confuse a quart with a pint. One pint is 473 ml, while one quart is 946 ml. A quart is twice a pint.
For labels or nutrition panels, follow the package units. For cooking conversions from US recipes, treat 1 quart as 946 ml unless the recipe states a different measuring system.
US Quart Versus Imperial Quart
A US liquid quart is 946 ml. An imperial quart is about 1,137 ml. The imperial quart is larger by about 191 ml, which is roughly 20% more liquid.
For US cooking, measuring cups, food labels, and most American recipes use the US quart. On crystalgood.net, “1 quart” means 4 US cups, or 946 ml, unless imperial is named.
Quick comparison
| Quart type | Cups or fluid ounces | Milliliters | Best assumption |
|---|---|---|---|
| US liquid quart | 4 US cups | 946 ml | Use for US recipes |
| Imperial quart | 40 imperial fl oz | about 1,137 ml | Use for UK-style measures |
The practical difference is not small. If a soup recipe needs 1 US quart of broth, use 946 ml. If you pour 1 imperial quart, you add about 191 ml extra.
That extra amount is more than 3/4 US cup, since 1 US cup is 237 ml. In baking, custards, sauces, and gelled desserts, that can noticeably thin the result.
Worked kitchen examples
Example 1: A US recipe calls for 2 quarts of stock. Use 1,892 ml, because 946 ml × 2 = 1,892 ml.
Example 2: If a British recipe calls for 2 imperial quarts, that is about 2,274 ml. Using 2 US quarts instead gives only 1,892 ml, short by about 382 ml.
Example 3: A pot labeled 4 quarts in the US holds about 3,784 ml. That is just under the listed US gallon value of 3.79 litres.
Example 4: Four imperial quarts equal about 4,548 ml. Compared with 4 US quarts, that is about 764 ml more, or a little over 3 US cups.
Edge cases that cause mistakes
If a recipe says only “quart” and uses US cups, US tablespoons, Fahrenheit oven temperatures, or US grocery terms, treat it as 946 ml.
If the recipe uses “imperial,” “UK quart,” or imperial fluid ounces, do not substitute 946 ml. Use about 1,137 ml per quart.
Do not confuse a US quart with a liter. A US quart is 946 ml, so it is 54 ml less than 1 liter. In most soups that is minor; in precise formulas it matters.
For scaling, multiply the number of US quarts by 946. For example, 1/2 US quart is 473 ml, the same as 1 US pint.
For cup conversions, 1 US quart equals 4 cups. Since 1 cup is 237 ml, 4 cups equal 948 ml by cup math, while the standard quart listing is 946 ml.
That 2 ml rounding gap is normal in kitchen tables. For cooking, use the stated quart value: 1 US quart = 946 ml.

Fast Formula For Quarts To Ml
Multiply the number of quarts by 946. That gives the milliliters for US liquid quart measurements.
Formula: quarts × 946 = ml.
Example: 2 quarts × 946 = 1,892 ml. That is the same as 8 cups, since 1 quart equals 4 cups.
Example: 1/2 quart × 946 = 473 ml. This is also 1 pint or 2 cups.
Example: 1/4 quart equals 1 cup, so it is 237 ml. This is useful when reducing soup, stock, milk, or broth amounts.
Common Kitchen Amounts
| Amount Needed | Use This US Measure | Metric Amount |
|---|---|---|
| Small sauce amount | 1/4 cup | 59 ml |
| Half measuring cup | 1/2 cup | 118 ml |
| One measuring cup | 1 cup | 237 ml |
| Half quart | 2 cups | 473 ml |
| Full quart | 4 cups | 946 ml |
If a recipe calls for 1 quart of water, milk, stock, or juice, measure 946 ml. If your metric jug marks liters, 1 quart is just under 1 liter because 1 liter is 1,000 ml.
For 3/4 quart, combine 3 cups. Since each cup is 237 ml, 3 cups equals 711 ml by cup math. Using the quart fraction gives 946 × 0.75 = 709.5 ml.
That small difference comes from rounded kitchen equivalents. For cooking, use 710 ml for 3/4 quart unless your recipe requires exact lab-style measuring.
Tablespoon And Fluid Ounce Check
One quart equals 32 fluid ounces. Since 1 fluid ounce equals 30 ml, fluid-ounce math gives 32 × 30 = 960 ml.
The reference quart value is 946 ml. The 960 ml result is from rounded fluid-ounce conversions, so use 946 ml when the recipe says 1 quart.
One quart also equals 64 tablespoons. Since 1 tablespoon equals 15 ml, tablespoon math gives 64 × 15 = 960 ml.
Use tablespoon or fluid-ounce math for quick scooping. Use the quart value, 946 ml, when converting the whole quart directly.
For 4 quarts, use the gallon reference: 1 gallon equals 16 cups or 3.79 litres. That is the same kitchen-size container as 4 US quarts.
How To Convert Quarts
1 quart = 946 ml. For US kitchen measuring, that is the number to use. A quart is also 4 cups, 2 pints, 32 tablespoons, or 32 fluid ounces.
The fastest conversion is: quarts × 946 = millilitres. To go the other way, use: millilitres ÷ 946 = quarts.
Step-by-step quart conversion
- 1. Identify the amount in quarts. If the recipe says 1 quart, start with 1. If it says 2 quarts, start with 2. If it says 1/2 quart, start with 0.5.
- 2. Multiply by 946 for millilitres. For 1 quart: 1 × 946 = 946 ml. For 3 quarts: 3 × 946 = 2,838 ml.
- 3. Use cup equivalents when measuring in the kitchen. Since 1 quart = 4 cups and 1 cup = 237 ml, then 4 × 237 = 948 ml. The standard quart figure is 946 ml.
- 4. Convert smaller fractions carefully. For 1/2 quart: 946 ÷ 2 = 473 ml. That also equals 1 pint or 2 cups.
- 5. Convert 1/4 quart as 1 cup. Since 1 quart = 4 cups, 1/4 quart = 1 cup = 237 ml.
- 6. Convert millilitres back to quarts. For 1,892 ml: 1,892 ÷ 946 = 2 quarts. For 473 ml: 473 ÷ 946 = 0.5 quart.
Quick reference table
| Quarts | Kitchen equivalent | Millilitres |
|---|---|---|
| 1/4 quart | 1 cup | 237 ml |
| 1/2 quart | 1 pint / 2 cups | 473 ml |
| 1 quart | 4 cups | 946 ml |
| 2 quarts | 8 cups | 1,892 ml |
| 4 quarts | 1 gallon / 16 cups | 3.79 litres |
Worked examples
Example 1: A soup recipe calls for 1 quart of broth. Measure 946 ml, or use 4 cups if your measuring cups are marked in cups.
Example 2: You need 2 quarts of water. Multiply 2 × 946. The answer is 1,892 ml.
Example 3: You have a 473 ml container. Divide 473 by 946. The result is 0.5 quart, which is the same as 1 pint or 2 cups.
Example 4: A recipe needs 1/4 quart of cream. Because 1 quart is 4 cups, 1/4 quart is 1 cup, or 237 ml.
Edge cases that cause mistakes
Do not round 1 quart to 1,000 ml for recipes. That adds 54 ml, which is more than 3 tablespoons because 1 tablespoon is 15 ml.
For a gallon, do not multiply 946 ml by 4 and call it exact in litres. The reference equivalent is 1 gallon = 3.79 litres.
If a measuring jug shows cups, use 4 cups for 1 quart. If it shows millilitres, use 946 ml for 1 quart.
Common Kitchen Measuring Tips
1 US quart equals 946 ml. In kitchen terms, 1 quart is also 4 cups, 2 pints, 32 fluid ounces, or 64 tablespoons.
Use 946 ml when converting a US liquid quart. Do not round it to 1,000 ml unless the recipe clearly allows an approximate metric amount.
Fast quart conversions for recipes
| Amount | US measure | Metric |
|---|---|---|
| 1/4 quart | 1 cup | 237 ml |
| 1/2 quart | 2 cups / 1 pint | 473 ml |
| 3/4 quart | 3 cups | 711 ml |
| 1 quart | 4 cups | 946 ml |
| 1 gallon | 4 quarts / 16 cups | 3.79 litres |
For a recipe needing 2 quarts of broth, use 8 cups or 1,892 ml. That comes from 946 ml x 2.
For 1 1/2 quarts of water, use 6 cups. In metric, that is 946 ml + 473 ml = 1,419 ml.
For 3 quarts of milk, use 12 cups. In metric, that is 946 ml x 3 = 2,838 ml.
Measuring without a quart container
If your measuring cup shows only cups, fill it to 1 cup four times. Since 1 cup is 237 ml, 4 cups equals 948 ml by cup math, while the quart reference is 946 ml.
That 2 ml difference is from rounded kitchen equivalents. For cooking, follow the recipe’s unit. If it says 1 quart, use the quart mark or 946 ml.
If your tool has tablespoons only, 1 quart is 64 tablespoons. This is useful for scaling dressings, syrups, or small-batch liquids when no cup measure is available.
If your tool has fluid ounces, 1 quart is 32 fluid ounces. Since 1 fluid ounce is 30 ml, ounce math gives 960 ml, another rounded kitchen result.
For the closest match to a US quart on a metric jug, measure 946 ml. If the jug marks every 100 ml only, 900 ml is short and 1,000 ml is over by 54 ml.
Dry ounces are not fluid ounces
Do not convert 1 quart to ounces by weight. A fluid ounce measures volume; an ounce measures weight. The reference weight conversion is 1 ounce = 28.3 g.
For example, 32 fluid ounces equals 1 quart by volume. But 32 ounces by weight equals 907 g, not a liquid quart measurement.
Use volume units for water, stock, milk, cream, juice, oil, and vinegar. Use weight units for flour, sugar, butter, cheese, meat, and produce when the recipe gives ounces or grams.
Scaling quart amounts cleanly
To halve a 1-quart recipe, use 1 pint, 2 cups, or 473 ml. To quarter it, use 1 cup or 237 ml.
To double a 1-quart recipe, use 2 quarts, 8 cups, or 1,892 ml. To make four times as much, use 1 gallon, 16 cups, or 3.79 litres.
When precision matters, write the conversion before you start: 1 quart = 946 ml, 1/2 quart = 473 ml, 1/4 quart = 237 ml. This avoids mixing rounded cup and ounce math.
