How many dry ounces are in a cup?
A cup of flour measures about 4.4 oz, a cup of sugar about 7.1 oz, and a cup of butter about 8 oz.
- One US cup of all-purpose flour converts to 4.4 oz.
- One US cup of granulated sugar converts to 7.1 oz.
- One US cup of un-sifted powdered sugar converts to 4.2 oz.
- One US cup of chocolate chips converts to 6 oz.
When converting between cups and dry ounces (oz) it's important to remember that the cup is a unit of volume and the dry ounce (oz) is a unit of weight. This means that the density of the substance needs to be factored into the conversion. As an example, a cup of flour weighs less than a cup of butter (4.4 ounces versus 8 ounces).
