How Much Is 0.21 Teaspoons of Cornstarch in Grams?
Converting 0.21 teaspoons of cornstarch to grams gives 0.56 g. One teaspoon of cornstarch weighs 2.67g, so 0.21 teaspoons is 0.21 × 2.67 = 0.56g. This conversion is specific to cornstarch because each ingredient has a different density.
Formula and Step-by-Step
- Start with 0.21 teaspoons of cornstarch
- 1 teaspoon of cornstarch = 2.67g
- 0.21 × 2.67 = 0.56g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Different flour types have very different weights per cup. Always check the specific flour your recipe calls for rather than using a generic "flour" conversion.

Understanding the Units
What is a Teaspoon?
A US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.
What is a Gram?
Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.
