How to Convert Ounces to Fluid Ounces

Scales are used to measure weight

To convert an ounce measurement to a fluid ounce measurement, divide the weight by 1.043176 times the density of the ingredient or material.

You can use this simple formula to convert:

fluid ounces = ounces1.043176 × ingredient density

Thus, the weight in fluid ounces is equal to the ounces divided by 1.043176 times the density of the ingredient or material.

For example, here's how to convert 5 ounces to fluid ounces for an ingredient with a density of 0.7 g/mL.
5 oz = 51.043176 × 0.7 = 6.847224 fl oz

Ounces and fluid ounces are both commonly used to measure cooking ingredients.

For cooking applications, most chefs suggest measuring dry ingredients by weight rather than volume to improve accuracy in the measurements.[1] The density of dry ingredients can vary for a variety of reasons, such as compaction.

The best way to ensure an accurate conversion is to use a scale. When a scale is not available, a calculator like the one above is a good way to estimate the weight to volume conversion.

Ounces

One ounce is a unit of mass/weight equal to 1/16 of a pound. The common ounce should not be confused with the troy ounce, which is equal to 1/12 of a troy pound.[2]

The ounce is a US customary and imperial unit of weight. Ounces can be abbreviated as oz; for example, 1 ounce can be written as 1 oz.

Fluid Ounces

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 an "ounce" but should not be confused with the unit of mass. One fluid ounce is equal to just under 29.6 milliliters, but in nutrition labeling, one fluid ounce is rounded to exactly 30 milliliters.[3]

The fluid ounce is a US customary unit of volume. Fluid ounces can be abbreviated as fl oz, and are also sometimes abbreviated as fl. oz. or oz. fl.. For example, 1 fluid ounce can be written as 1 fl oz, 1 fl. oz., or 1 oz. fl..
