Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 120g/cup × 16 = tablespoons
  1. Start with 16.89 ounces of powdered sugar
  2. Convert ounces to grams: 16.89 × 28.35 = 478.82g
  3. 1 cup of powdered sugar = 120g
  4. 478.82g ÷ 120g/cup = 3.99 cups × 16 = 63.84 tablespoons

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.

Frequently Asked Questions

About 63.84 tbsp, 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), then multiply by 16 to get tablespoons. For 16.89 ounces: 16.89 × 28.3495 = 478.82g, then 478.82 ÷ 120 = 3.99 cups × 16 = 63.84 tbsp.
For the most accurate results, weigh powdered sugar on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring spoon and level it off with a straight edge rather than scooping directly.
Granulated and powdered sugars should be spooned into the measuring spoon and leveled off. Do not pack them unless the recipe specifically says to.
Reverse the conversion: 63.84 tbsp ÷ 16 = 3.9902 cups, then 3.9902 × 120g/cup = 478.82g, then 478.82g ÷ 28.3495 = 16.89 ounces. Or use the Tablespoons to Ounces converter.
