To convert a pound measurement to a cup measurement, multiply the flour by the conversion ratio.

Since one pound of flour is equal to 3.628739 cups, you can use this simple formula to convert:

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.
