25 g of powdered sugar in cups
25 g ≈ 0.21 cups
That is also 3.33 tablespoons, at 120 g per US cup.
How to measure it
3 tablespoons + 1 teaspoon
0.21 cups is a number, not an instruction — there is no 0.21 cup in the drawer. The line above is the same quantity in the sizes you actually own, and following it lands within a teaspoon of 25 g.
Spoon the powdered sugar into the cup and level it off. Scooping straight from the bag packs it down; on flour that alone is worth about 20%, which is more than the difference this page is measuring.

Why this number moves
Very light and prone to lumps. Sift before measuring if the recipe depends on a smooth result.
This page uses 120 g per US cup. If your recipe came with its own figure, use theirs — internal consistency matters more than which table is right.

Frequently asked questions
How many cups is 25 g of powdered sugar?
0.21 cups, which in measuring cups and spoons is 3 tablespoons + 1 teaspoon. One US cup of powdered sugar weighs about 120 g.
How do I measure 25 g of powdered sugar without scales?
3 tablespoons + 1 teaspoon. Spoon it in and level the top rather than scooping — scooping compacts powdered sugar and can add a fifth to the weight.
Is this the same in the UK?
The gram figure is, the cup is not. A US cup is 236.6 ml and the metric cup used in Australia and much of Europe is 250 ml, so a European cup of powdered sugar weighs about 127 g. These pages use the US cup.
