Formula and Step-by-Step

cups × 120g/cup ÷ 453.592g/lb = pounds
  1. Start with 10.31 cups of powdered sugar
  2. 1 cup of powdered sugar = 120g
  3. 10.31 × 120 = 1,237.2g
  4. Convert grams to pounds: 1,237.2 ÷ 453.592 = 2.73 lb

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.

Frequently Asked Questions

About 2.73 lb, 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 453.592 to convert grams to pounds. For 10.31 cups: 10.31 × 120 = 1,237.2g, then 1,237.2 ÷ 453.592 = 2.73 lb.
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: 2.73 lb × 453.592 = 1,237.2g, then 1,237.2g ÷ 120 = 10.31 cups. Or use the Pounds to Cups converter.
