How Much Is 4 Cups of Brown Sugar in Pounds?
4 cups of brown sugar equals 1.94 lb. Brown sugar has a density of 220g per cup (220g per cup), which means it's relatively heavy compared to other common cooking ingredients. For comparison, 4 cups of all-purpose flour would be 1.10 lb.
Formula and Step-by-Step
- Start with 4 cups of brown sugar
- 1 cup of brown sugar = 220g
- 4 × 220 = 880g
- Convert grams to pounds: 880 ÷ 453.592 = 1.94 lb
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Brown sugar should always be firmly packed into the measuring cup. Loosely measured brown sugar can weigh 15-20% less than packed.

Understanding the Units
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
What is a Pound?
The abbreviation "lb" comes from the Latin word "libra." One pound equals exactly 453.59237 grams. For rough mental math, 1 pound is slightly less than half a kilogram.
