Why weight beats volume for powdered sugar
A cup is a volume; a recipe cares about mass. Powdered sugar runs about 120 g per US cup measured spoon-and-level, but packing, humidity, and grind can move that by ±10%. Weighing removes the guesswork, which is exactly why serious baking recipes list grams.
Unsifted. Sifted powdered sugar runs closer to 100 g per cup.

Frequently asked questions
How many grams is ¾ cup of powdered sugar?
¾ cup of powdered sugar is about 90 g (3.17 oz), based on 120 g per US cup, measured spoon-and-level.
Why does the ingredient change the answer?
Cups measure volume, grams measure weight. Dense ingredients pack more weight into the same cup: a cup of honey is 340 g while a cup of rolled oats is only 90 g. That is why generic cup-to-gram converters get recipes wrong.
Does it matter how I fill the cup?
Unsifted. Sifted powdered sugar runs closer to 100 g per cup.
Is this a US cup or a metric cup?
A US customary cup (236.6 mL). A metric cup is 250 mL, about 5.7% bigger, and old UK recipes use a 284 mL imperial cup. ¾ cup here is 177 mL by volume.
