Ounces to Cups Converter
There is no single answer for ounces to cups, because ounces measure weight and cups measure volume. The answer depends on the ingredient: 8 ounces of all-purpose flour is 1.814 cups. The familiar rule that 8 ounces make a cup is true only for water and similar liquids, where weight ounces and fluid ounces nearly match.

The math behind it: Ounces to Cups
volume = weight / density
Choose your ingredient above and the calculator applies its typical density. Dry goods are assumed to be spooned into the cup and leveled off; scooping straight from the bag packs in up to 20% more.
