Are icing sugar and Powdered Sugar the same thing?

Icing Sugar Measurement Converter

Use the tool below to convert icing sugar from the measurements in your recipe to the measurements that you need.

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, so 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.

Related to Icing Sugar

Sugar

Granulated sugar is the coarse crystal that icing sugar is milled from, and it is heavier per cup (200 g vs 125 g), so it will not dissolve smoothly in frostings. Blend it to a fine powder first, or weigh rather than swapping by volume. See our Sugar converter.

Raw Sugar

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.
