How Much Is 40 Tablespoons of Powdered Sugar in Ounces?
40 tablespoons of powdered sugar equals 10.58 oz. Powdered sugar has a density of 120g per cup (7.5g per tablespoon), which means it's relatively light compared to other common cooking ingredients. For comparison, 40 tablespoons of honey would be 29.98 oz.
Formula and Step-by-Step
- Start with 40 tablespoons of powdered sugar
- 1 tablespoon of powdered sugar = 7.5g
- 40 × 7.5 = 300g
- Convert grams to ounces: 300 ÷ 28.3495 = 10.58 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.
