1 US cup = 236.588 mL. Grams are typical values per cup from the King Arthur Baking Ingredient Weight Chart: flour is spooned and leveled, so scooping straight from the bag weighs more. Weigh when a recipe lists grams. More ingredients: see the clevr.tools/calc/convert/cooking

6 cups is 1,419.5 mL (US cups, 1 cup = 236.588 mL). That is 96 tablespoons (288 teaspoons), or 48 US fluid ounces.
That is 1.42 litres, so 6 cups of water or any other liquid is 1,420 mL.
How this is calculated
Every conversion goes through one base unit, the liter: the input is converted to liters, then from liters to the unit you chose.
Formulas
1 US cup is one sixteenth of a US gallon, and a US gallon is defined as 231 cubic inches.
1 cup = 231 in³ ÷ 16 = 14.4375 in³
One inch is exactly 25.4 millimeters, so a cup works out to 236.5882365 mL. The converter uses 0.236588 L (236.588 mL), which NIST also lists to six digits.
1 cup = 14.4375 × 25.4³ mm³ = 236.5882365 mL
Spoon and ounce units follow the US customary definitions.
1 cup = 8 fl oz = 16 tbsp = 48 tsp
To convert, multiply by the source unit's size in liters and divide by the target unit's size in liters.
mL = cups × 236.588
Sources
- NIST Special Publication 811, Guide for the Use of the International System of Units. Defines the SI units and how US customary units relate to them.

How we test this
This tool is checked against independent formulas every time the site is released, and a release does not ship if a check fails. Example from the test suite: 2.25 US cups gives 532.32 mL. The test computes 2.25 × 231 × 25.4³ ÷ 16 mm³ on its own, without calling the converter, and checks the converter agrees.
The test is “cups-to-ml: 2.25 US cups = 532.32 mL” in tests/unit-conversion-golden.test.mjs. More on how all tools are tested: our testing approach.
Assumptions and limits
- US customary cups, not metric cups (250 mL), imperial cups (284 mL) or the 240 mL cup on US nutrition labels.
- Volume only. Ingredient weights depend on the ingredient, so this page converts volume to volume and does not give grams.
- The converter's factors carry six significant digits, so results can differ from the exact definition by up to about 0.0002%.

When to use this
You are following a recipe from an American cookbook and it calls for 1 3/4 cups of milk, but your measuring tools are metric. Or you found a great recipe online from a European site measured in milliliters and you only have cup measures in your kitchen. This conversion comes up every time a recipe crosses the Atlantic — American recipes use cups, while most of the rest of the world measures liquids in milliliters and liters.
The standard US cup equals 236.588 mL. This is different from the metric cup used in Australia (250 mL) and the imperial cup used in older British recipes (284 mL), so always check which system a recipe is using. When this converter says "cup," it means the US customary cup — the one printed on every American measuring cup set.
Good to know
A US cup is not exactly 250 mL. It is 236.588 mL. This 14 mL difference seems small but can matter in baking, where precision counts. If a recipe calls for 4 cups of flour and you round up to 1,000 mL (4 x 250), you will add about 54 mL too much — enough to noticeably affect a cake's texture.
Australian and UK cups are different sizes. The Australian metric cup is exactly 250 mL. The old imperial cup (UK) is 284 mL. If you are following a recipe from an Australian cookbook and you are in the US, your cups will measure slightly less than intended. For cooking this usually does not matter; for baking, it can.
Weighing is more accurate than volume for dry ingredients. A "cup of flour" can vary by 20–30% depending on how you scoop it. Professional bakers weigh ingredients in grams. But for liquids — water, milk, broth — volume measurements are perfectly accurate, and cups-to-mL conversion gives you precise results.
