Formula and Step-by-Step

cups × 120g/cup = grams
  1. Start with 3.31 cups of powdered sugar
  2. 1 cup of powdered sugar = 120g
  3. 3.31 × 120 = 397.2g

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 Cup?

In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.

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.

Frequently Asked Questions

About 397.20 g, based on powdered sugar having a density of 120g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 120 (grams per cup for powdered sugar). For 3.31 cups: 3.31 × 120 = 397.20 g.
For the most accurate results, weigh powdered sugar on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
Granulated and powdered sugars should be spooned into the measuring cup and leveled off. Do not pack them unless the recipe specifically says to.
Reverse the conversion: 397.20 g ÷ 120 = 3.31 cups. Or use the Grams to Cups converter.
