Formula and Step-by-Step

teaspoons × 2.67g/tsp ÷ 28.3495g/oz = ounces

Start with 9.39 teaspoons of cornstarch
1 teaspoon of cornstarch = 2.67g
9.39 × 2.67 = 25.04g
Convert grams to ounces: 25.04 ÷ 28.3495 = 0.88 oz

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 an Ounce?

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.

Frequently Asked Questions

How many ounces is 9.39 teaspoons of cornstarch? expand_more

About 0.88 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.

What is the formula for converting teaspoons of cornstarch to ounces? expand_more

Multiply the number of teaspoons by 2.67 (grams per teaspoon for cornstarch), then divide by 28.3495 to convert grams to ounces. For 9.39 teaspoons: 9.39 × 2.67 = 25.04g, then 25.04 ÷ 28.3495 = 0.88 oz.

How do I measure cornstarch accurately? expand_more

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.

Does the measurement method affect how much cornstarch weighs per cup? expand_more

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.
