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:

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

While experts usually suggest measuring dry ingredients by weight since it's more accurate,^[1] some recipes call for ingredients by volume and many of us don't have a scale when we need one. Because the density of different types of sugar vary, it may not be obvious how to convert between a weight and volume measurements.

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

Should I 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 vary slightly, so volume measurements will likely yield an incorrect amount of ingredient. 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.

This is why most experts suggest using a food scale to measure sugar when cooking, rather than a cup, tablespoon, or other volume measuring devices.

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