Convert cups to fluid ounces
fluid ounces = cups × 8
One cup is 8 fluid ounces, so multiply by 8 to convert. That factor is exact by definition. This is the US customary cup of 236.588 mL. Nutrition labels use a 240 mL cup and metric recipes a 250 mL one; the difference is under 6%, which matters for baking and not much else. This is the US fluid ounce of 29.5735 mL. An imperial (UK) fluid ounce is 28.4131 mL — smaller, because there are 20 to an imperial pint rather than 16.
