A pound of all-purpose flour is about 3.6 cups when spooned and leveled. Because flour packs down, this varies, so a pound can range from about 3.3 to 3.6 cups depending on how it is measured. For accuracy, weigh flour rather than relying on the cup count.
1 pound all-purpose flour is about 3.6 cups (spooned and leveled).
Why It Is Not Exact
A pound is 454 grams, and a cup of all-purpose flour is about 120 to 125 grams spooned in, giving roughly 3.6 cups. But packing the flour raises the grams per cup and lowers the cup count, so treat this as an approximation.
Weigh for Baking
When a recipe or a bag lists flour by weight, weigh it. It is far more reliable than converting to cups, which vary with how you scoop.
Quick Reference
| Flour type | Cups per pound |
|---|---|
| All-purpose | ~3.6 cups |
| Bread flour | ~3.5 cups |
| Cake flour | ~4 cups |
| Whole wheat | ~3.6 cups |
