How to Convert Pounds of Flour to Cups

To convert a pound measurement to a cup measurement, multiply the flour by the conversion ratio. One pound of flour is equal to 3.628739 cups, so use this simple formula to convert:

cups = pounds × 3.628739

The flour in cups is equal to the pounds multiplied by 3.628739.

For example, here's how to convert 5 pounds to cups using the formula above.
5 lb = (5 × 3.628739) = 18.143695 c

While most experts suggest measuring dry ingredients by weight for improved precision,[1] not all recipes call for ingredients by weight and when they do we might not all have a scale handy. Because flours vary in density, it might not be immediately clear how to convert between a weight and volume measurement.

The table below can help with the conversion, and shows the approximate volume measurement for various weights of flour, by type.

Should I 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 ingredient. Additionally, the amount that the flour is packed or compressed in the cup or tablespoon will alter the amount of ingredient being added.

For these reasons, a food scale is the preferred way to measure flour when cooking, rather than a cup or tablespoon.

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

Pounds

A pound is a commonly used unit to measure flour weight. A pound of flour is equal to 16 ounces, and there are 0.453592 kilograms in one pound.

The pound is a US customary and imperial unit of flour. Pounds can be abbreviated as lb, for example 1 pound can be written as 1 lb.

Cups

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 flour. 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.
