Frequently Asked Questions
How many grams is a cup of powdered sugar?
1 cup of unsifted powdered sugar is 113 grams.
What should I know about measuring powdered sugar?
This conversion is for unsifted powdered sugar, and powdered sugar is much lighter per cup than granulated sugar because it's ground finer and holds more air — sifting it first can lower the weight per cup slightly further, so measure before sifting for the most standard result.
Should I use a kitchen scale instead of cups?
For baking specifically, yes if precision matters — weight doesn't vary with how tightly an ingredient is packed, so it's more consistent than volume measurement. This converter helps translate a cup-based recipe to weight, or a weight-based recipe back to cups.
