Understanding how many ounces (oz) are in a cup is essential for accuracy. The number of ounces in a cup depends on whether you’re measuring liquid or dry ingredients.
- For liquids: 1 cup = 8 fluid ounces (fl oz)
- For dry ingredients: The weight in ounces varies depending on the ingredient’s density.
So, 1 cup equals 8 fl oz for liquids, but for dry ingredients, the weight in ounces varies by density. Read the complete post for more details!
