There is no single answer to how many cups are in a pound, because a pound measures weight and a cup measures volume. Butter is 2 cups per pound, all-purpose flour is 3.6 cups, granulated sugar is 2.25 cups, and powdered sugar is 3.75 cups.
This guide includes a cups-per-pound chart by ingredient, along with conversions for 2 pounds, a 5-pound bag of flour, and different sugar types. It also shares tips for accurate measuring to get reliable results.
How Many Cups Are in a Pound?
Water, flour, and butter all weigh differently per cup because they pack together at different densities.
Ingredient
Cups per Pound
Water
1.92 cups
Butter
2 cups (4 sticks)
Granulated sugar
2.25 cups
All-purpose flour
3.6 cups
Brown sugar
2.4 cups
Powdered sugar
3.75 cups
These figures come from standard density-based conversions used across cooking references and kitchen calculators. A kitchen scale is still the most reliable tool if you want exact precision.
