Powdered Sugar Grams to Cups
Convert grams of powdered sugar to cups and cups of powdered sugar to grams, starting from 100 g, which is about 7/8 cup. Powdered sugar, icing sugar and confectioners sugar are one ingredient under three names, and it is far lighter by the cup than granulated: 120 g to a US cup spooned in and levelled, against 200 g for granulated, so swapping one for the other cup for cup puts a recipe a long way out.
Powdered (icing) sugar: 120 g in one US cup, a density of 0.5072 g per mL. Source: Spooned and levelled convention.

Common questions
- How many cups is 100 g of powdered sugar?
- 0.8333 cups, about 7/8 cup, at 120 g per spooned US cup. 200 g is 1.667 cups, about 1 5/8 cups, and 250 g is 2.083 cups, about 2 1/8 cups. The converter above starts on 100 g; change the amount to convert a different weight.
- How many grams is 1 cup of powdered sugar?
- 120 g, spooned into the cup and levelled off, which is the convention this figure comes from. Half a cup is 60 g and a quarter cup is 30 g. Powdered sugar packs down easily, so a cup pressed in or scooped from the bag weighs more than this, which is the case for weighing it.
- Are icing sugar and confectioners sugar the same as powdered sugar?
- Yes. All three names mean sugar ground to a fine powder, usually with a little anti-caking agent mixed in. The ingredient list above carries it once, as Powdered (icing) sugar, so the figure is the same whichever name the recipe uses.
- Is a metric cup of powdered sugar a different weight?
- Slightly. A metric cup is 250 mL against the US cup's 236.588 mL, so a metric cup of powdered sugar holds 126.8 g rather than 120 g. The tool has a switch for the metric cup, and it moves the tablespoon to 15 mL and the teaspoon to 5 mL at the same time. The table on this page is for the US cup.
Cups measure volume and grams measure mass, so the answer depends on the ingredient; the density used is shown beside every result with its source. Flour differs by about 12 percent between spooned and scooped, and both are listed.
