How Much Is a Fluid Ounce?

The US fluid ounce is a unit of volume equal to 1/16 of a pint or 1/8 of a cup. The fluid ounce is sometimes referred to as just an "ounce" but should not be confused with the unit of weight. One fluid ounce is equal to approximately 29.5735 milliliters, but in nutrition labeling, one fluid ounce is rounded to exactly 30 milliliters.[1]

How to Convert Fluid Ounces

To convert fluid ounces to another unit of volume, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[2]

You can find the conversion factors for fluid ounces in the conversion table below.

Then, multiply the volume measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

fluid ounces × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
