8 US fluid ounces = 1 US cup
Converter Calculator
1 Fluid Ounces = 0.125 Cups
Explanation
Divide US fluid ounces by 8 because 1 US cup contains that exact number of US fluid ounces, so the math stays inside the customary volume definitions. That keeps beverage pours comparable to cup-based recipes without leaving the familiar units.
It helps you read pint, ounce, or beverage servings in the same cup increments while decimals stay supported so partial pours remain precise. Keeping the definitions anchored to the same customary values prevents drift when switching between ounces and cups.
