How to measure powdered sugar accurately

For the most reliable baking results, weigh powdered sugar on a kitchen scale rather than scooping by volume. One US cup of powdered sugar weighs about 120 grams, but the exact figure changes with how tightly it's packed and the brand. Use the table above for quick reference, or the converter for any custom amount.
