Convert fluid ounces to cups
cups = fluid ounces × 0.125
One fluid ounce is 0.125 cups, so multiply by 0.125 to convert. That factor is exact by definition. 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. 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.
