How Much Is 6.35 Ounces of Powdered Sugar in Cups?

6.35 ounces of powdered sugar equals 1.50 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

(ounces × 28.35g/oz) ÷ 120g/cup = cups
  1. Start with 6.35 ounces of powdered sugar
  2. Convert ounces to grams: 6.35 × 28.35 = 180.02g
  3. 1 cup of powdered sugar = 120g
  4. 180.02g ÷ 120g/cup = 1.50 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 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.

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.

Frequently Asked Questions

About 1.50 cups, 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.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 120 (grams per cup). For 6.35 ounces: 6.35 × 28.3495 = 180.02g, then 180.02 ÷ 120 = 1.50 cups.
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: 1.50 cups × 120g/cup = 180.02g, then 180.02g ÷ 28.3495 = 6.35 ounces. Or use the Cups to Ounces converter.
