How Much Is 3.31 Cups of Brown Sugar in Pounds?
3.31 cups of brown sugar weighs 1.61 lb. This is based on brown sugar having a density of 220g per cup. Because cups measure volume and pounds measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 3.31 cups.
Formula and Step-by-Step
- Start with 3.31 cups of brown sugar
- 1 cup of brown sugar = 220g
- 3.31 × 220 = 728.2g
- Convert grams to pounds: 728.2 ÷ 453.592 = 1.61 lb
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
If your brown sugar has hardened, microwave it with a damp paper towel for 20 seconds. Hard brown sugar is still the same weight but impossible to measure by volume.

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?
Pounds are the standard weight unit for buying ingredients in the US. A standard bag of flour is 5 pounds (2,268g) and a standard bag of sugar is 4 pounds (1,814g).
