This free mL to cups converter turns milliliters into US cups, with the amounts recipes use most.
It gives the exact cup and the nearest measure you can pour, like ½ cup or 2⅛ cups.
I built it because metric recipes measure liquids in milliliters, US measuring cups don't, and a cup isn't a round number of milliliters.
Here's the exact size of a cup, a worked example, and why 240 mL shows up on labels.
TL;DRKey takeaways
What is a mL to cups converter?
A mL to cups converter turns a volume in milliliters into US cups.
It's for metric recipes in a US kitchen, and the other way round.
How big is a cup?
NIST Handbook 44 defines the US cup as 8 fluid ounces, and a fluid ounce as 29.573 53 mL. So a cup is about 236.6 mL, which NIST rounds to 237 mL.

| 125 mL | ½ cup |
| 250 mL | 1 cup (1.06) |

A worked example
Here's the example the calculator loads: 250 mL.
250 ÷ 236.6 = 1.06 cups, a cup plus about a tablespoon.
Mistakes to avoid
These are the slips that come up most.
- Using a cup from another country's set, which can hold a different amount
