How the cups to ml conversion works

The US cup is defined as 236.588 ml, so the conversion is a single multiplication: ml = cups × 236.588. Going the other way, cups = ml ÷ 236.588.

Worked example: a recipe calling for 2 cups of milk needs 2 × 236.588 = 473.176 ml. A 750 ml bottle holds 750 ÷ 236.588 ≈ 3.17 cups.

Watch out for the metric cup (250 ml) used in Australia and New Zealand — it is about 6% larger than the US cup, which is enough to throw off a cake. When a recipe just says “cup” and the source is American, it means the US cup used here.
