Formula and Step-by-Step

tablespoons × 7.5g/tbsp ÷ 28.3495g/oz = ounces
  1. Start with 3.78 tablespoons of powdered sugar
  2. 1 tablespoon of powdered sugar = 7.5g
  3. 3.78 × 7.5 = 28.35g
  4. Convert grams to ounces: 28.35 ÷ 28.3495 = 1.00 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.

Frequently Asked Questions

About 1.00 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 tablespoons by 7.5 (grams per tablespoon for powdered sugar), then divide by 28.3495 to convert grams to ounces. For 3.78 tablespoons: 3.78 × 7.5 = 28.35g, then 28.35 ÷ 28.3495 = 1.00 oz.
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: 1.00 oz × 28.3495 = 28.35g, then 28.35g ÷ 7.5 = 3.78 tablespoons. Or use the Ounces to Tablespoons converter.
