Powdered Sugar Grams to Cups: Chart & Calculator
Converting powdered sugar grams to cups is different from converting granulated or brown sugar because powdered sugar is much lighter and finer. Grams To Cup Hub uses 120 grams per US cup of powdered sugar. That means 60g equals ½ cup, 120g equals 1 cup, 250g is about 2.08 cups, and 500g is about 4.17 cups.
1 US cup of powdered sugar = 120 grams. That means 30g = ¼ cup, 60g = ½ cup, 120g = 1 cup, and 500g ≈ 4.17 cups.

How Many Grams Are in 1 Cup of Powdered Sugar?
Grams To Cup Hub uses 120 grams per US cup of powdered sugar. That means ½ cup equals 60g, ¼ cup equals 30g, and 2 cups equal 240g.
Powdered sugar is finely ground, so it behaves differently from regular sugar crystals. It can also hold air and form lumps, which makes weighing more reliable than volume for precision-sensitive baking.

How to Convert Powdered Sugar Grams to Cups
Cups = Grams ÷ 120
For example:
120g ÷ 120g per cup = 1 cup
250g ÷ 120g per cup ≈ 2.08 cups
500g ÷ 120g per cup ≈ 4.17 cups

Powdered Sugar vs Icing Sugar vs Confectioners’ Sugar
In many recipes, powdered sugar, icing sugar, and confectioners’ sugar refer to the same general type of finely ground sugar. Naming varies by country and brand.
Some products may contain a small amount of anti-caking ingredient such as starch, so exact density can vary slightly. For the site’s general conversion, we use 120g per US cup.
Sifted vs Unsifted Powdered Sugar
Sifting breaks up lumps and adds air between particles. Because of this, a cup measured after sifting may not weigh exactly the same as a cup scooped from a settled container.
Should Powdered Sugar Be Packed?
No. Powdered sugar is generally not packed the way brown sugar is. Pressing it firmly into a cup can increase the amount of sugar and change the recipe balance.
For a normal volume measurement, spoon it lightly into the cup and level the top, unless the recipe gives another instruction.
Powdered Sugar vs Granulated and Brown Sugar
Sugar type makes a large difference when converting grams to cups. The same 1-cup volume can have very different weights depending on the ingredient.
| Sugar Type | Grams per US Cup | ½ Cup | Measurement Note |
|---|---|---|---|
| Powdered Sugar | 120g | 60g | Light, fine powder |
| Granulated Sugar | 200g | 100g | Loose crystals |
| Brown Sugar | 213g | 106.5g | Packed |

Powdered Sugar Cups, Tablespoons, and Teaspoons
For smaller icing and frosting recipes, tablespoons or teaspoons can be useful. Using our site reference, one tablespoon of powdered sugar is about 7.5g.
| Powdered Sugar Measure | Approx. Grams | Cups | Kitchen Measure |
|---|---|---|---|
| 1 teaspoon | 2.5g | ≈0.021 cup | 1 tsp |
| 1 tablespoon | 7.5g | 0.0625 cup | 3 tsp |
| ¼ cup | 30g | 0.25 cup | 4 tbsp |
| ½ cup | 60g | 0.50 cup | 8 tbsp |
| ¾ cup | 90g | 0.75 cup | 12 tbsp |
| 1 cup | 120g | 1 cup | 16 tbsp |
How to Measure Powdered Sugar Accurately
If the sugar has lumps, loosen it gently before measuring. Sift it only when the recipe asks you to do so.
When using a measuring cup, spoon the sugar lightly into the cup and level the top without pressing it down.
For frostings, glazes, and delicate baking, weighing powdered sugar in grams is usually the simplest way to get repeatable results.
US Cup vs Metric Cup for Powdered Sugar
Our main powdered sugar chart uses the US customary cup of 236.588 ml. The calculator also supports US Legal, Metric, and Imperial cup standards.
| Cup Standard | Volume | Typical Use |
|---|---|---|
| US Customary Cup | 236.588 ml | Default on Grams To Cup Hub |
| US Legal Cup | 240 ml | Food labeling |
| Metric Cup | 250 ml | Many metric recipes |
| Imperial Cup | 284.131 ml | Older Imperial references |
For general kitchen measurement equivalencies, see the NIST Metric Kitchen measurement guide .
Why Powdered Sugar Conversion Charts Can Differ
Published values can vary because powder fineness, brand formulation, anti-caking ingredients, sifting, settling, cup size, and rounding all affect a volume measurement.
