Fluid Ounce (US) to Cup (US) (Fluid Ounce (US) to Cup (US))
Result
0.125 Cup (US)
Formula
Cup (US) = Fluid Ounce (US) × 0.125
1 Fluid Ounce (US) = 0.125 Cup (US), and 1 Cup (US) = 8 Fluid Ounce (US).
Kitchen volumes here are US customary measures: 1 cup = 236.588 mL, 1 tablespoon = 14.787 mL, 1 teaspoon = 4.929 mL, 1 fluid ounce = 29.574 mL. Weights use the avoirdupois ounce and pound.
Worked examples
- 1 Fluid Ounce (US) × 0.125 = 0.125 Cup (US)
- 10 Fluid Ounce (US) × 0.125 = 1.25 Cup (US)
- 100 Fluid Ounce (US) × 0.125 = 12.5 Cup (US)
Common mistakes
- Cups measure volume and grams measure weight. Converting between them depends on the ingredient: a cup of flour weighs roughly 120–130 g, a cup of sugar about 200 g.
- Cup sizes vary: US customary 236.6 mL, US nutrition label 240 mL, metric (Australia, Canada, UK recipes) 250 mL.
- An Australian tablespoon is 20 mL (four teaspoons), not 15 mL.
