How many grams is ⅓ cup of powdered sugar (unsifted)?
Answer
40 g
⅓ cup of powdered sugar (unsifted) is about 40 grams, or 1.4 ounces. That works out from USDA's figure of roughly 120 g for a full US cup (236.6 mL).
This is for unsifted powdered sugar. Sifting adds air, so a cup of sifted sugar weighs less.

Measuring tip
For sticky syrups, give the cup a light coat of oil first so everything slides out and you get the full amount. Brown sugar is the one sugar that is normally packed firmly into the cup.
