How to convert fluid ounces to cups

cups = fluid ounces × 0.125

US measuring cups and spoons are fixed ratios: 1 cup = 16 tablespoons = 48 teaspoons = 8 fluid ounces = 236.6 ml.

Fluid ounces or weight ounces?

Recipes use "ounces" for both. Fluid ounces measure volume: 8 fl oz = 1 cup of anything. Ounces by weight depend on the ingredient: 8 oz of flour is 1.81 cups, 8 oz of sugar is 1.13 cups. For weight, set "From" to Ounces (oz) above and pick the ingredient.
