How to Convert Ounces to Cups

Save Share Tweet

To convert an ounce measurement to a cup measurement, divide the weight by 8.345404 times the density of the ingredient or material.

You can use this simple formula to convert:

cups = ounces8.345404 × ingredient density

Thus, the weight in cups is equal to the ounces divided by 8.345404 times the density of the ingredient or material.

For example, here's how to convert 5 ounces to cups for an ingredient with a density of 0.7 g/mL.

5 oz = 58.345404 × 0.7 = 0.855903052319 c

This calculator converts ounces in weight, if you're trying to convert a volume measurement in fluid ounces try our fluid ounces to cups calculator.

Ounces and cups 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.

For cooking and baking ingredients, you can get more specific results using our butter, flour, sugar conversion calculators.

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.

Cups

The cup is a unit of volume equal to 16 tablespoons or 8 fluid ounces. The cup should not be confused with the metric cup or the teacup, which are different units of volume. One cup is equal to just under 236.6 milliliters, but in nutrition labeling, one cup is equal to 240 milliliters.^[3]

The cup is a US customary unit of volume. Cups can be abbreviated as c, and are also sometimes abbreviated as C. For example, 1 cup can be written as 1 c or 1 C.
