How Much Is 20 Grams of Powdered Sugar in Cups?
20 grams of powdered sugar equals 0.17 cups. Powdered sugar has a density of 120g per cup. Because grams measure weight and cups measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 20 grams of powdered sugar
- 1 cup of powdered sugar = 120g
- 20g ÷ 120g/cup = 0.17 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Powdered sugar clumps easily. Sift before measuring by volume, or weigh to avoid the sifted-vs-unsifted ambiguity entirely.

Understanding the Units
What is a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
What is a Cup?
The US cup (236.588 ml) is slightly smaller than the metric cup used in Australia and some other countries (250 ml). When following recipes from different countries, check which cup standard is being used.
