How to convert pounds to cups
cups = pounds × 1.91722
Example: 5 lb × 1.91722 = 9.586 cups.
Multiply the pounds by the number of cups that one pound of the ingredient fills. The formula above is set for water, while flour, sugar and other foods each have their own figure in the converter.
By USDA figures, a pound of granulated sugar fills about 2.268 cups. A 4 lb bag therefore holds 4 × 2.268 = 9.1 cups.
Butter needs no math at all. A pound is 4 sticks, each marked 1/2 cup, so the whole pound makes 2 cups. For the opposite direction, use the cups to pounds converter.
US vs UK cups
| Unit | Size | Used in |

| US cup | 236.6 ml | US |
| US legal cup | 240 ml | US nutrition labels |
| metric cup | 250 ml | UK, Australia, Canada, New Zealand |
Why weight depends on the ingredient
A pound is a fixed weight, but the number of cups it fills depends on how much room the food takes up. Dense foods such as butter and sugar fill few cups, while light, airy ones such as flour and powdered (icing) sugar fill many.
Produce shows the same spread. Diced raw potatoes fill about 3.02 cups per pound and raw garlic about 3.34 cups, because the pieces leave gaps that a liquid would fill.
| Ingredient | 1 lb = |
|---|---|
| All-purpose flour | 3.629 cups |
| Granulated sugar | 2.268 cups |
| Butter | 1.998 cups |
| Milk | 1.859 cups |
| Powdered sugar | 3.78 cups |
| Shredded cheese | 4.014 cups |
Turning a package weight into cups
Packaged flour, sugar and cheese carry a net weight, not a cup count (21 CFR 101.7). A quick conversion tells you whether one package covers a recipe. These figures use the USDA cup weights behind the converter:
- 2 lb of all-purpose (plain) flour: about 7.3 cups
- 2 lb of powdered sugar: about 7.6 cups
- 8 oz of shredded cheese: about 2 cups
- 3 lb of potatoes, diced: about 9 cups
Plan on a little less than these figures, since packing flour or cheese into the cup uses up a package faster.
Pounds and cups: questions
Is a pound 2 cups?
Only for a few foods. Butter comes out at exactly 2 cups per pound, and water at 1.92 cups. Flour, powdered sugar and cheese are much lighter for their size, so a pound of each fills far more cups.
How many cups of flour are in a pound?
About 3.63 cups of all-purpose flour, based on the USDA weight of a cup. USDA does not say whether its cup was spooned or scooped. A cup dipped straight into the bag packs in more flour, so you get fewer cups from each pound.
How many cups is a pound of powdered sugar?
About 3.78 cups of unsifted powdered sugar. Sifting adds air between the grains, so a sifted pound fills even more cups. Weigh it when a frosting recipe gives grams or ounces.
How many cups of blueberries are in a pound?
A pound of whole raw blueberries fills about 3.06 cups. Blackberries are a little lighter per cup, so a pound of them fills about 3.15 cups. Measure berries loosely, without pressing them into the cup.
How many cups is half a pound of sugar?
Half a pound of granulated sugar fills about 1.13 cups. Half a pound of butter, by contrast, is 2 sticks, or exactly 1 cup, because butter packs more weight into each cup than sugar does.
