Pounds to Cups Converter
Convert pounds to cups for cooking and baking ingredients. Since pounds measure weight and cups measure volume, the conversion depends on the density of the ingredient. This calculator converts pounds to US cups for flour, sugar, butter, and other common ingredients used in recipes.
How to Convert Pounds to Cups
First convert pounds to grams (1 lb = 453.59 g), then divide by the ingredient's grams-per-cup value. For example, 1 pound of flour = 453.59 ÷ 120 = 3.78 cups.

Frequently Asked Questions
How many cups is 1 pound of flour?
1 pound of all-purpose flour equals approximately 3.78 cups. This is based on 120 grams per cup using the spoon-and-level method.
How many cups is 1 pound of sugar?
1 pound of granulated sugar equals approximately 2.27 cups. Sugar is denser than flour, so a pound fills fewer cups.
How many cups is 1 pound of butter?
1 pound of butter equals 2 cups (4 sticks). Each stick of butter is ½ cup or 113.5 grams.
Why can't I use a single conversion for all ingredients?
Because cups measure volume and pounds measure weight. Different ingredients have different densities, so 1 pound of a light ingredient (flour) fills more cups than 1 pound of a dense ingredient (honey).
