How to convert mL to cups
Divide the milliliters by 236.588, the number of milliliters in one US customary cup. Because the US cup is defined as 8 US fluid ounces, that divisor is exact; for everyday use 236.6 is plenty.
A 400 mL carton holds 400 ÷ 236.588 = 1.69 cups, so a bit over 1 2/3 cups. A 180 mL glass of juice is 0.76 cups, almost exactly three quarters of a cup. A full liter is 4.23 cups.
Measuring cups only come in a few sizes, so the table also gives the nearest amount you can actually pour: whole cups plus 1/4, 1/3, 1/2, 2/3 or 3/4, and tablespoons for very small amounts.
US cups = milliliters ÷ 236.5882365 (≈ milliliters × 0.00422675)
- The US customary cup is 8 US fluid ounces, 236.5882365 mL; food labels round it to 240 mL. Source: 21 CFR 101.9(b)(5), FDA nutrition labelling.
How to estimate mL to cups in your head
Divide by 250 and add 5%. A US cup is 5% smaller than a quarter of a liter, so the quick quotient comes out a little low: 400 ÷ 250 = 1.6, and 1.6 + 0.08 = 1.68 cups, against an exact 1.69.
Another way: every 60 mL is a quarter cup (59.15 mL, to be exact), so 180 mL is three quarter-cups.
