1/4 Cup of Powdered Sugar in Grams
1/4 cup of powdered sugar weighs 30 grams (about 1.1 oz), based on 120 g per US cup (spoon-and-level method). That's the same as 4 tablespoons of powdered sugar. When a recipe's outcome depends on accuracy — especially baking — weigh it instead of measuring by cup.
A 1/4 cup measure is the smallest scoop in a standard set, so this one you almost certainly own. Two of them make 1/2 cup (60 g) and four make a full cup (120 g).

No 1/4 cup measure? Use spoons
1/4 cup is exactly 4 tablespoons, which is 30 g of powdered sugar. Measuring spoons are stamped to a tighter tolerance than cups, so for small amounts the spoon route is usually the more accurate one even when you do own the cup.
Halving and doubling 1/4 cup
Scaling a recipe is the usual reason this conversion comes up, and grams scale cleanly where cup fractions do not:
| Recipe | Cups | Grams | Spoons |
|---|---|---|---|
| Half | ⅛ cup | 15 g | 2 tablespoons |
| As written | ¼ cup | 30 g | 4 tablespoons |
| Double | ½ cup | 60 g | 8 tablespoons |
