Icing sugar is a finely milled white sugar with a light, silky texture. One metric cup weighs approximately 125 grams (4.41 oz), noticeably lighter than granulated sugar because the fine particles don't pack as tightly. It's used in buttercreams, glazes, frostings, and as a dusting over cakes and pastries.

Icing sugar is so fine and airy that the amount you get in a cup can vary significantly depending on how it's scooped — measuring by weight gives far more consistent results. This page lets you convert icing sugar between grams, cups, tablespoons, and more so your recipes turn out reliably every time.

  • Powdered Sugar
  • Confectioners' Sugar

Granulated sugar is the coarse, crystalline form that icing sugar is milled from. It is heavier by cup (200 g vs 125 g) and creams into butter for cakes, whereas icing sugar suits frostings and dusting, so the two are not a straight 1:1 swap. See our Sugar converter.

Raw sugar has large, coarse crystals with a faint molasses taste, far removed from the fine powder of icing sugar. It packs much heavier (200 g vs 125 g per cup), so the two are not a straight swap. See our Raw Sugar converter.
