Grams to cups: powdered sugar

Working the other way — a recipe in grams, and cups are what you have in the drawer:

Grams of powdered sugar Cups (approx.)
50 g 0.44 cup
100 g ⅞ cup
125 g 1⅛ cups
200 g 1¾ cups
250 g 2¼ cups
500 g 4.42 cups

Why the measuring method matters

The 113 g figure assumes powdered sugar unsifted, straight from the bag. Sifting aerates it, so a cup of sifted powdered sugar weighs less than this. A scale removes the variable entirely, and it is the reason professional recipes are written in weight.
