A metric cup (250 ml, used in Australia, New Zealand, Canada and many Indian recipes) holds about 6% more than a US cup.
Granulated sugars are levelled; brown sugar is packed firmly into the cup. Syrups are easiest to measure in a lightly oiled cup.
Unsifted. Sifted powdered sugar weighs about 100 g per cup.
Also called: icing sugar, confectioners' sugar.
Weights are for a level US cup (236.6 ml) and level spoons, from King Arthur Baking's ingredient weight chart. Brands and packing vary by a few per cent; when a recipe gives grams, weigh rather than measure.
1 level US cup of powdered sugar weighs about 113 g (4 oz). A 250 ml metric cup weighs about 119 g.
1 level tablespoon of powdered sugar is about 7.1 g, and 1 teaspoon is about 2.4 g.
100 g of powdered sugar is about 0.88 cups, or 14.2 tablespoons.
A cup measures volume, not weight. Powdered Sugar is full of air between the particles, so a cup weighs much less than a cup of water (113 g vs 237 g).
