How Many Milliliters Are in a Cup?
How many ml in a cup when the recipe is American? 236.588 ml — usually rounded to 237 ml in the kitchen.
Canada, Australia, New Zealand and most of the world use the metric cup: a cup in ml is exactly 250.
Pre-1970s British recipes may mean the imperial cup, which is noticeably larger than the US cup.
Convert Cups to ml
Converting cups to ml is one of the most common calculations in any kitchen. American recipes measure liquids and dry ingredients in cups, while almost everywhere else — food labels, measuring jugs, kitchen scales — works in milliliters. That mismatch ruins bakes and waters down sauces every single day. This guide explains exactly how many ml are in a cup, which cup size your recipe means, and how to convert cups to ml (and back) with total confidence.
How to Convert Cup (US) to Milliliter
The conversion factor never changes: 1 US cup = 236.5882365 ml. So the formula is simple:
milliliters = cups × 236.5882365
Multiply your cups figure by 236.5882365, round to the nearest whole milliliter, and you are done. Example: convert 15 US cups to ml: 15 × 236.5882365 = 3548.8235475 ml, which rounds to 3,549 ml. The converter above applies this exact factor instantly, so you never have to do the multiplication yourself.
How to Convert Milliliters to Cups
To go the other way, divide your milliliter figure by the size of your cup:
cups = milliliters ÷ 236.5882365 (US cup)
Example: 473 ml ÷ 236.5882365 = 1.999 cups — in other words, exactly 2 US cups. That is why 473 ml cans and bottles are the classic “2-cup” size in American supermarkets. For metric recipes, divide by 250 instead. The “nearest fraction” column in our ml to cups chart shows the closest measuring-cup fraction, so you can grab the right cup without mental math.
What Is a Cup?
A cup is a unit of volume in the imperial and United States customary systems of measurement. The US customary cup — the one American recipes mean — is legally defined as 236.5882365 milliliters, equal to 8 US fluid ounces, 16 US tablespoons, 48 US teaspoons, and exactly 1/16 of a US gallon.
Cooks reach for the cup to measure liquids like milk and stock and bulk dry foods like flour and sugar, often in the context of serving sizes. Note that actual drinking cups vary wildly in size and are never a reliable measure — only standardized measuring cups give the true cup volume. Outside the US, the metric cup (250 ml) is standard in Canada, Australia and New Zealand, while old British recipes sometimes mean the imperial cup (284.131 ml).
What Is a Milliliter?
A milliliter (symbol: mL) is a unit of volume accepted for use with the International System of Units. One milliliter equals exactly one cubic centimeter, one-thousandth of a liter, and one-millionth of a cubic meter.
The word “milliliter” comes from the French litre, itself derived from the older litron. In everyday life, milliliters measure the volume of small containers — bottles, cans, juice cartons, yogurt pots — and graduated cylinders, beakers and kitchen jugs are all marked in ml. Because the milliliter is a true international standard, it never changes between countries, which is exactly why converting cups to ml removes the guesswork from international recipes.
US Cup vs Metric Cup vs Imperial Cup
Not all cups are equal, and this is where most conversion mistakes happen. A “1 cup” difference between the US and metric cup is 13.4 ml — nearly 6% — enough to throw off a delicate cake. The rule of thumb: American recipes mean the US cup; Canadian, Australian and New Zealand recipes usually mean the metric cup; pre-1970s British recipes may mean the imperial cup.
| Cup standard | Milliliters per cup | Used in |
|---|---|---|
| US customary cup | 236.588 ml | United States; American recipes |
| Metric cup | 250 ml | Canada, Australia, New Zealand, most of the world |
| UK imperial cup | 284.131 ml | Pre-1970s British recipes |
When in doubt, check the recipe’s origin — or use the cup-standard selector in the converter above to convert with the right size.
Common Cups to ml Values in the Kitchen
Memorize a few anchor values and everyday converting gets effortless: 1 cup to ml = 236.588 ml (US), usually rounded to 237 ml; 1.5 cups in ml = 354.88 ml, about 355 ml; 0.75 cup in ml = 177.44 ml, about 177 ml — the same answer whether you search “0.75 cup in ml” or “0.75 cups to ml”; 5 cups in ml = 1,182.94 ml, about 1.18 liters; and 4 cups stock in ml = 946.35 ml, just under a liter — handy, because most stock cartons are sold in 1-liter sizes.
Going the other way: how many cups is 473 ml? Divide by 236.588 and you get exactly 2 cups. Keep these anchors in mind and you will rarely need to reach for a calculator mid-recipe.
Cups to Milliliters in Cooking and Baking
Baking is chemistry, and chemistry dislikes vague measurements — which is why serious bakers convert cups to ml and then weigh ingredients in grams. Liquids convert cleanly: 1 cup of milk is 237 ml whether you are in New York or New Delhi.
Dry ingredients are trickier: a cup of flour weighs about 120 g while a cup of sugar weighs about 200 g, because volume and weight are different things. Use this cups-to-ml converter for liquids, and our cups to grams converter for dry ingredients. For broths and stocks — where recipes say “4 cups stock” — the ml value (946 ml) lets you measure directly in a metric jug without touching a cup measure at all.
Tips for Accurate Cup-to-ml Conversions
First, confirm your cup standard before you convert — US versus metric is the single biggest source of error. Second, for baking, round to the nearest milliliter; for everyday cooking, rounding to the nearest 5 ml is perfectly fine. Third, measure liquids at eye level in a clear jug and read the bottom of the meniscus. Fourth, never use a coffee mug as a “cup” — mugs range from 200 to 400 ml. Fifth, when a recipe gives both cups and ml and the two disagree, trust the milliliters: the metric values are the precise ones. Finally, bookmark this page — an instant answer beats mental math when your hands are covered in flour.
