Formula and Step-by-Step

cups × 120g/cup ÷ 28.3495g/oz = ounces

Start with 1.55 cups of powdered sugar
1 cup of powdered sugar = 120g
1.55 × 120 = 186g
Convert grams to ounces: 186 ÷ 28.3495 = 6.56 oz

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 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 an Ounce?

Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
