To convert milliliters to US cups, divide by 236.588. So 100 ml = 0.42 cups, 250 ml = 1.06 cups, and 500 ml = 2.11 cups. 1 US cup = 236.588 ml (not 240 or 250 ml, though recipes often round up).
- Formula: cups = ml ÷ 236.588. 1 US cup = 236.588 ml exactly.
- 60 ml = 1/4 cup. 120 ml = 1/2 cup. 180 ml = 3/4 cup. 240 ml ≈ 1 cup (slight rounding).
- 250 ml = 1.057 cups - metric recipes often round this to "1 cup".
- Reverse: ml = cups × 236.588.
