How Much Is 0.45 Cups of Powdered Sugar in Grams?
0.45 cups of powdered sugar weighs 54.00 g. This is based on powdered sugar having a density of 120g per cup. Because cups measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 0.45 cups.
Formula and Step-by-Step
- Start with 0.45 cups of powdered sugar
- 1 cup of powdered sugar = 120g
- 0.45 × 120 = 54g
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.
Powdered Sugar at Different Amounts
How powdered sugar scales across common cups measurements. Your amount (0.45 cups) is highlighted.
For reference, 0.45 cups of powdered sugar (54g) is close in weight to a whole large egg (57g).

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?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
