How Much Is 3.99 Teaspoons of Cornstarch in Grams?
3.99 teaspoons of cornstarch weighs 10.64 g. This is based on cornstarch having a density of 128g per cup. Because teaspoons measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 3.99 teaspoons.
Formula and Step-by-Step
- Start with 3.99 teaspoons of cornstarch
- 1 teaspoon of cornstarch = 2.67g
- 3.99 × 2.67 = 10.64g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Humidity affects cornstarch weight. In humid conditions, flour absorbs moisture and weighs more per cup. Store it in an airtight container for consistent results.
