How Much Is 120 Grams of Powdered Sugar in Cups?
Converting 120 grams of powdered sugar to cups gives 1.00 cup. Divide by the density of powdered sugar (120g per cup). Each ingredient fills a different volume at the same weight.
Formula and Step-by-Step
- Start with 120 grams of powdered sugar
- 1 cup of powdered sugar = 120g
- 120g ÷ 120g/cup = 1 cup
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Powdered sugar settles significantly during storage. Sifted powdered sugar weighs about 100g per cup compared to 120g unsifted - check whether your recipe means sifted or unsifted.

Understanding the Units
What is a Gram?
Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.
What is a Cup?
There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.
