Formula and Step-by-Step

teaspoons × 2.67g/tsp = grams
  1. Start with 42.51 teaspoons of cornstarch
  2. 1 teaspoon of cornstarch = 2.67g
  3. 42.51 × 2.67 = 113.36g

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?

In baking, teaspoon measurements are critical for ingredients where precision changes the outcome. Too much baking soda (1 tsp = 6g) creates a metallic taste, while too little means flat results.

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.

Frequently Asked Questions

About 113.36 g, based on cornstarch having a density of 128g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 2.67 (grams per teaspoon for cornstarch). For 42.51 teaspoons: 42.51 × 2.67 = 113.36 g.
For the most accurate results, weigh cornstarch on a kitchen scale. If measuring by volume, sift or whisk first to break up clumps, then spoon into the measuring spoon and level off. Do not scoop directly from the bag.
Yes, quite a bit. If you spoon the flour into your measuring spoon and level it off, you will get about 128 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 140.8 to 160 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
Reverse the conversion: 113.36 g ÷ 2.67 = 42.51 teaspoons. Or use the Grams to Teaspoons converter.
