How it works
Milliliter = US cup × 236.5882. Every value is converted through a single liter base unit using internationally defined conversion factors, so any from/to pair stays consistent.
Good to know
Converting cups to milliliters is something home cooks reach for constantly, usually when following a recipe written in the US but cooking with a metric kitchen scale or a measuring jug marked only in millilitres. Baking is where it matters most: getting liquids right by volume keeps batters, doughs, and sauces behaving the way the recipe author intended, especially since metric measuring cups sold in Europe and Australia are not the same size as a US cup.
The mismatch comes down to two different measuring traditions. The millilitre is a metric unit, one-thousandth of a litre, used almost everywhere outside the United States. The US customary cup, by contrast, is an imperial-descended kitchen measure legally defined as exactly 236.5882 mL. That is why a single US cup is an awkward number rather than a tidy round figure on a metric jug.
For quick mental math, just round a US cup to about 237 mL, or even a flat 240 mL if you only need ballpark accuracy (240 is the "legal" or nutrition-labeling cup the FDA uses). A handy chain: half a cup is roughly 118 mL, a quarter cup is about 59 mL, and a tablespoon is around 15 mL.
The most common mistake is assuming all cups are equal. A US customary cup is 236.6 mL, but a US "legal" cup is 240 mL, a metric cup (UK/Australia/NZ) is 250 mL, and an old UK imperial cup was about 284 mL. Grabbing the wrong one can throw a recipe off by 10 percent or more, so confirm which cup a recipe means before converting.
Frequently asked questions
How do you convert us cup to milliliter?
Multiply the number of us cups by 236.5882 to get milliliters. For example, 1 cup = 236.5882 mL.
What is 1 us cup in milliliters?
1 us cup equals 236.5882 milliliters (1 cup = 236.5882 mL).
How many us cups are in 1 milliliter?
There are 0.004226753 us cups in 1 milliliter.
Is this converter free and private?
Yes. It runs entirely in your browser, so your inputs never leave your device, there is no sign-up, and it works offline once loaded.
Are the conversions exact?
Conversions use internationally defined factors and are exact where the definitions are exact (for example, 1 inch = 2.54 cm). Displayed results are rounded for readability.
People also ask
How many mL is 2 cups?
Two US cups equal about 473.18 mL (2 × 236.5882). For everyday cooking you can round that to roughly 473 mL, or about half a litre.
Is a cup 250 mL or 240 mL?
Neither matches the US customary cup, which is 236.5882 mL. A metric cup used in Australia, the UK and New Zealand is 250 mL, while the US FDA 'legal' cup for nutrition labels is 240 mL.
How many mL in half a cup?
Half a US cup is 118.29 mL (236.5882 ÷ 2). Most cooks just round it to 118 mL or 120 mL.
How many mL is three quarters of a cup?
Three-quarters of a US cup is 177.44 mL (236.5882 × 0.75), commonly rounded to 177 mL.
How many mL is a quarter cup?
A quarter US cup is 59.15 mL (236.5882 ÷ 4), usually rounded to about 59 mL or 60 mL.
How many cups is 250 mL?
250 mL is about 1.057 US cups, so just over one US cup. In a metric measuring system, however, 250 mL is exactly one metric cup.
How do I convert mL back to cups?
Divide the millilitres by 236.5882 to get US cups. For example, 500 mL ÷ 236.5882 is about 2.11 cups.
Does the cups-to-mL conversion change for dry ingredients?
No. The cup-to-mL factor measures volume only and stays 236.5882 mL per US cup regardless of the ingredient. The ingredient's weight in grams differs, but its volume in millilitres does not.
Is 1 cup 200 mL or 250 mL?
It depends on which cup the recipe means. A US customary cup, the one this converter uses, is 236.5882 mL; the metric cup used in Australia, New Zealand, Canada, and other metric countries is 250 mL; and the traditional Japanese cup is 200 mL. For most cooking the 236.6 versus 250 mL gap is minor, but a 200 mL cup is about 15 percent smaller than a US cup, so check the recipe's origin before scaling up.
