How Much Is 1 Cup of Powdered Sugar in Pounds?
1 cup of powdered sugar equals 0.26 lb. Powdered sugar has a density of 120g per cup (120g per cup), which means it's relatively light compared to other common cooking ingredients. For comparison, 1 cup of honey would be 0.75 lb.
Formula and Step-by-Step
- Start with 1 cup of powdered sugar
- 1 cup of powdered sugar = 120g
- 1 × 120 = 120g
- Convert grams to pounds: 120 ÷ 453.592 = 0.26 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?
There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.
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.
