Cup & Gram

3/4 Cup of Powdered Sugar in Grams

3/4 cup of powdered sugar weighs 90 grams (about 3.2 oz), based on 120 g per US cup (spoon-and-level method). That's the same as 12 tablespoons of powdered sugar. When a recipe's outcome depends on accuracy — especially baking — weigh it instead of measuring by cup.

Almost no measuring set has a 3/4 cup. Build it as 1/2 cup + 1/4 cup (60 g + 30 g), or as 3 × 1/4 cup (30 g each).

No 3/4 cup measure? Use spoons

3/4 cup is exactly 12 tablespoons, which is 90 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 3/4 cup

Scaling a recipe is the usual reason this conversion comes up, and grams scale cleanly where cup fractions do not:

How to measure 3/4 cup of powdered sugar

These values are for unsifted powdered sugar, spooned into the cup and leveled (120 g). If your recipe says "sifted powdered sugar," sift first and expect closer to 100 g per cup — sifting adds a lot of air.
