How many ounces in a cup?

The number of ounces in a cup can vary depending on whether you are measuring liquid or dry ingredients.

Liquid Ingredients (Fluid Ounces)

In the United States, one cup is equivalent to 8 fluid ounces. Here are some conversions for liquid ingredients:

• 1 cup = 8 fluid ounces135
• ¾ cup = 6 fluid ounces
• ½ cup = 4 fluid ounces
• ¼ cup = 2 fluid ounces

Dry Ingredients (Dry Ounces)

For dry ingredients, the weight in ounces per cup varies depending on the density of the ingredient. Here are some examples:

• 1 cup of all-purpose flour ≈ 4.4 ounces345
• 1 cup of granulated sugar ≈ 7.1 ounces345
• 1 cup of butter ≈ 8 ounces34

It is important to note that dry ingredients should ideally be measured by weight rather than volume for accuracy, as their densities can vary significantly345.
