Formula and Step-by-Step

cups × 120g/cup ÷ 28.3495g/oz = ounces
  1. Start with 51.54 cups of powdered sugar
  2. 1 cup of powdered sugar = 120g
  3. 51.54 × 120 = 6,184.8g
  4. Convert grams to ounces: 6,184.8 ÷ 28.3495 = 218.16 oz

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Powdered sugar clumps easily. Sift before measuring by volume, or weigh to avoid the sifted-vs-unsifted ambiguity entirely.

Frequently Asked Questions

About 218.16 oz, 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), then divide by 28.3495 to convert grams to ounces. For 51.54 cups: 51.54 × 120 = 6,184.8g, then 6,184.8 ÷ 28.3495 = 218.16 oz.
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: 218.16 oz × 28.3495 = 6,184.8g, then 6,184.8g ÷ 120 = 51.54 cups. Or use the Ounces to Cups converter.
