Formula and Step-by-Step

tablespoons × 8g/tbsp ÷ 28.3495g/oz = ounces
  1. Start with 21.26 tablespoons of cornstarch
  2. 1 tablespoon of cornstarch = 8g
  3. 21.26 × 8 = 170.08g
  4. Convert grams to ounces: 170.08 ÷ 28.3495 = 6.00 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 Tablespoon?

A tablespoon is roughly the volume of a large soup spoon. In precise terms, 1 US tablespoon equals 14.787 ml, which is very close to the 15 ml metric standard used in most of the world. Three teaspoons make one tablespoon.

What is an Ounce?

Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.

Frequently Asked Questions

About 6.00 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 tablespoons by 8 (grams per tablespoon for cornstarch), then divide by 28.3495 to convert grams to ounces. For 21.26 tablespoons: 21.26 × 8 = 170.08g, then 170.08 ÷ 28.3495 = 6.00 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.
Reverse the conversion: 6.00 oz × 28.3495 = 170.08g, then 170.08g ÷ 8 = 21.26 tablespoons. Or use the Ounces to Tablespoons converter.
