Like grams to cups, “cups in a pound” has no universal answer — it depends on the ingredient’s density. A pound (454 grams) of a light, fluffy ingredient fills more cups than a pound of a dense one. Divide 454 by the ingredient’s grams-per-cup.
By ingredient

| Granulated sugar | ~2.25 cups |

Frequently asked questions
How many cups of flour in a pound? About 3.6 cups of all-purpose, spooned and leveled.
How many cups in a pound of butter? Exactly 2 cups, or 4 sticks.
Why does it vary by ingredient? A pound is weight; a cup is volume, and densities differ.
This is also why baking recipes increasingly list weights: a pound of flour is a fixed amount, but “3.6 cups” depends entirely on how you scoop. When precision matters, a kitchen scale removes the variability that measuring by cup introduces.
A quick example shows why this matters: “1 pound of powdered sugar” is roughly 3.75 cups, but the same pound of granulated sugar is only about 2.25 cups — nearly a cup-and-a-half difference for the same weight. Reaching for the wrong one throws off both texture and sweetness, exactly the kind of error that weighing on a scale eliminates entirely.
