Metric cups and other cup sizes
The figures above use the US customary cup of 236.6 ml. A metric cup is 250 ml, so a metric cup of powdered sugar weighs about 127 grams. UK recipes that say "cup" usually mean a 250 ml metric cup, which is why weighing in grams is more reliable than measuring by volume.
Measuring powdered sugar accurately
Sift powdered sugar before measuring if your recipe calls for sifted sugar, as sifting aerates it significantly. If unsifted, spoon it gently into the cup and level the top without tapping. Powdered sugar compacts easily, making weight measurements far superior to volume for precise results.
