To convert a measurement in ounces to a measurement in cups, multiply the flour by the following conversion ratio: 0.226796 cups/ounce.

Since one ounce of flour is equal to 0.226796 cups, you can use this simple formula to convert:

cups = ounces × 0.226796

The flour in cups is equal to the flour in ounces multiplied by 0.226796.

How Many Cups Are in an Ounce of Flour?

There are 0.226796 cups in an ounce of flour, which is why we use this value in the formula above.

1 oz = 0.226796 c

Experts often recommend measuring dry ingredients by weight for accuracy,^[1] but some recipes use volume, and not all home cooks own a digital scale. Converting between weight and volume can be tricky because different types of flour vary in density.

The table below can help with the conversion and shows the approximate volume measurement for the weight of various types of flour.

Should You Measure Flour by Weight or Volume?

Most experts agree that dry ingredients like flour should be measured by weight rather than volume, especially in baking. The reason for this is that flours vary slightly in density, so a volume measurement will likely yield an incorrect amount of ingredients. Additionally, the amount that the flour is packed or compressed in the cup or tablespoon will alter the amount of ingredients being added.

For these reasons, a food scale, rather than measuring cups or spoons, is the preferred way to measure flour when cooking. For recipes that call for measurements in volume, professional bakers use a whisk to aerate flour that's been stored in a bag or canister before measuring since flour will settle when stored and weigh heavier even in the same-sized measuring cup.
