How Much Is 1.5 Cups of Powdered Sugar in Pounds?
1.5 cups of powdered sugar weighs 0.40 lb. This is based on powdered sugar having a density of 120g 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 1.5 cups.
Formula and Step-by-Step
- Start with 1.5 cups of powdered sugar
- 1 cup of powdered sugar = 120g
- 1.5 × 120 = 180g
- Convert grams to pounds: 180 ÷ 453.592 = 0.40 lb
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Powdered sugar settles significantly during storage. Sifted powdered sugar weighs about 100g per cup compared to 120g unsifted - check whether your recipe means sifted or unsifted.

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).
