How many grams in 1 cup of powdered sugar?
1 cup of powdered sugar weighs about 120 grams (4.2 oz). Sift before measuring if the recipe says so, since it clumps and changes the weight.
Cups to grams, for your ingredient
A cup of flour and a cup of honey weigh very differently. Pick the ingredient, enter the amount, and read it in any unit.
Weights are typical averages (US cup, 240 ml). Packing and brand change them by a few percent, so for baking a kitchen scale is more exact.
