How Much Is 400 Grams of Powdered Sugar in Cups?
400 grams of powdered sugar equals 3.33 cups. Powdered sugar has a density of 120g per cup. A lighter ingredient like cocoa powder (86g/cup) would fill even more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 400 grams of powdered sugar
- 1 cup of powdered sugar = 120g
- 400g ÷ 120g/cup = 3.33 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Powdered sugar dissolves faster than granulated, making it ideal for frostings and glazes. Weight is the most reliable way to measure it consistently.

Understanding the Units
What is a Gram?
A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.
What is a Cup?
The US cup (236.588 ml) is slightly smaller than the metric cup used in Australia and some other countries (250 ml). When following recipes from different countries, check which cup standard is being used.
