Formula and Step-by-Step

teaspoons × 2.67g/tsp ÷ 28.3495g/oz = ounces
  1. Start with 240 teaspoons of cornstarch
  2. 1 teaspoon of cornstarch = 2.67g
  3. 240 × 2.67 = 640g
  4. Convert grams to ounces: 640 ÷ 28.3495 = 22.58 oz

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

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.

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 an Ounce?

Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.

Frequently Asked Questions

About 22.58 oz, 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), then divide by 28.3495 to convert grams to ounces. For 240 teaspoons: 240 × 2.67 = 640g, then 640 ÷ 28.3495 = 22.58 oz.
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.
