Convert 2 cups to ml: 2 × 236.588 = 473.18 ml — one US pint, which is exactly two cups.
When you need this
Recipes from the US list cups while kitchen scales and jug measures everywhere else read millilitres, so every translated recipe passes through this number. Baby-formula prep, cocktail batches and bread-machine pans all ask for it too. Watch out for UK recipes — their historical cup is 284 ml, not 236.59.
