What Is the Fluid Ounces to Cups Converter?
This tool converts a volume measured in US fluid ounces (fl oz) into US cups. It's handy for cooking, baking, and following recipes where ingredients may be listed in either unit. The conversion is based on the standard US customary measurement where one cup equals exactly 8 fluid ounces.
How to Use It
Enter the number of fluid ounces you want to convert into the input field and the calculator instantly displays the equivalent number of cups. You can enter whole numbers or decimals (for example, 12.5 fl oz).
The Formula Explained
The conversion uses a simple division: $$\text{Cups} = \frac{\text{Fluid Ounces (fl oz)}}{8}$$ Because there are 8 fluid ounces in a single US cup, dividing your fluid-ounce amount by 8 gives the number of cups. To go the other way, multiply cups by 8 to get fluid ounces.
Worked Example
Suppose a recipe calls for 24 fluid ounces of broth. Divide 24 by 8: $$24 \div 8 = 3$$ So 24 fluid ounces equals 3 cups.
FAQ
How many cups are in 8 fluid ounces? Exactly 1 cup, since \(1 \text{ cup} = 8 \text{ fl oz}\).
Does this use US or UK measurements? This converter uses US customary units, where \(1 \text{ cup} = 8\) US fluid ounces. UK (imperial) measurements differ.
How many cups is 16 fluid ounces? \(16 \div 8 = 2\) cups, which is also equal to 1 US pint.
