To convert a measurement in ounces to a measurement in cups, multiply the sugar by the following conversion ratio: 0.141748 cups/ounce.

Since one ounce of sugar is equal to 0.141748 cups, you can use this simple formula to convert:

cups = ounces × 0.141748

The sugar in cups is equal to the sugar in ounces multiplied by 0.141748.

How Many Cups Are in an Ounce of Sugar?

There are 0.141748 cups in an ounce of sugar, which is why we use this value in the formula above.

1 oz = 0.141748 c

Experts often recommend measuring dry ingredients by weight for accuracy,^[1] but some recipes use volume, and many home cooks don't own a digital scale. Converting between weight and volume can be tricky depending on sugar densities such as granulated, brown sugar, or powdered sugar.

This table shows the approximate volume measurement for various weights of various types of sugar to help with the conversion.

Should You Measure Sugar by Weight or Volume?

Many experts are adamant that dry ingredients like sugar should be measured by weight instead of volume, especially when used for baking.

The reason is that the density of different sugars varies slightly, so volume measurements will likely yield an incorrect amount of ingredients. Additionally, when using a cup or tablespoon, the amount that the sugar is compressed and above or under the measurement line will alter the actual amount.

Experts recommend having a digital food scale on hand for measuring sugar rather than measuring spoons or cups for the most accurate results.

Ounces and cups are both units used to measure sugar. Keep reading to learn more about each unit of measure.
