How many solid ounces equals a cup?

Answer 1

An ounce (not a liquid ounce) is a measure of weight.
A cup is a measure of volume.
The number of ounces per cup will depend on the density of the material.

For example, an ounce of flour is bigger in volume (because it is less dense) than an ounce of sugar.

Answer 2

A cup is a unit of capacity. An ounce is a unit of mass. With no indication of density, the two units are therefore incompatible.

Answer 3

That is 1/4 cup.

Answer 4

1/4 cup.

Answer 5

1 CUP
