Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 128g/cup × 16 = tablespoons
  1. Start with 2.98 ounces of cornstarch
  2. Convert ounces to grams: 2.98 × 28.35 = 84.48g
  3. 1 cup of cornstarch = 128g
  4. 84.48g ÷ 128g/cup = 0.66 cups × 16 = 10.56 tablespoons

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.

Understanding the Units

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.

What is a Tablespoon?

One tablespoon holds about 15 milliliters. There are 16 tablespoons in a cup and 3 teaspoons in a tablespoon. In baking, tablespoon measurements are used for butter, oil, honey, and other ingredients where a full cup would be too much.

Frequently Asked Questions

About 10.56 tbsp, based on cornstarch having a density of 128g per cup. The exact amount depends on how the ingredient is measured and the specific product.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 128 (grams per cup), then multiply by 16 to get tablespoons. For 2.98 ounces: 2.98 × 28.3495 = 84.48g, then 84.48 ÷ 128 = 0.66 cups × 16 = 10.56 tbsp.
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: 10.56 tbsp ÷ 16 = 0.660012 cups, then 0.660012 × 128g/cup = 84.48g, then 84.48g ÷ 28.3495 = 2.98 ounces. Or use the Tablespoons to Ounces converter.
