Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 128g/cup × 16 = tablespoons
  1. Start with 10 ounces of cornstarch
  2. Convert ounces to grams: 10 × 28.35 = 283.50g
  3. 1 cup of cornstarch = 128g
  4. 283.50g ÷ 128g/cup = 2.21 cups × 16 = 35.44 tablespoons

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 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.

What is a Tablespoon?

Tablespoon sizes differ by country. A US tablespoon is 14.787 ml, close to the 15 ml metric standard used in most countries. An Australian tablespoon is 20 ml, about 35% larger than US. An imperial tablespoon is 17.758 ml. If your recipe comes from Australia, the larger tablespoon size can make a real difference.

Frequently Asked Questions

About 35.44 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 10 ounces: 10 × 28.3495 = 283.50g, then 283.50 ÷ 128 = 2.21 cups × 16 = 35.44 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: 35.44 tbsp ÷ 16 = 2.21481 cups, then 2.21481 × 128g/cup = 283.50g, then 283.50g ÷ 28.3495 = 10 ounces. Or use the Tablespoons to Ounces converter.
