How Much Is 1 Tablespoon of Cornstarch in Ounces?
Converting 1 tablespoon of cornstarch to ounces gives 0.28 oz. One tablespoon of cornstarch weighs 8g (0.28 oz). This conversion is specific to cornstarch because each ingredient has a different density.
Formula and Step-by-Step
- Start with 1 tablespoon of cornstarch
- 1 tablespoon of cornstarch = 8g
- 1 × 8 = 8g
- Convert grams to ounces: 8 ÷ 28.3495 = 0.28 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

For the most consistent results, weigh cornstarch on a kitchen scale. Volume measurements can vary by 20-30% depending on how the flour is scooped.
