How Much Is 3 Teaspoons of Cornstarch in Grams?
3 teaspoons of cornstarch equals 8.00 g. Cornstarch has a density of 128g per cup (2.67g per teaspoon), which means it's relatively light compared to other common cooking ingredients. For comparison, 3 teaspoons of honey would be 21.25 g.
Formula and Step-by-Step
- Start with 3 teaspoons of cornstarch
- 1 teaspoon of cornstarch = 2.67g
- 3 × 2.67 = 8g
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?
A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.
