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.

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

What Is an Ounce?

An ounce of flour is 1/16 of a pound, and there are 28.3495 grams in one ounce. An ounce is a measure of flour weight.

The ounce is a US customary and imperial unit of weight. Ounces can be abbreviated as oz; for example, 1 ounce can be written as 1 oz.

What Is a Cup?

The cup is a commonly used unit to measure flour volume. One cup of flour is equal to 16 tablespoons.

The cup is a US customary unit of volume. Cups can be abbreviated as c, and are also sometimes abbreviated as C. For example, 1 cup can be written as 1 c or 1 C.
