Formula and Step-by-Step

grams ÷ 128g/cup × 16 = tablespoons
  1. Start with 128 grams of cornstarch
  2. 1 cup of cornstarch = 128g
  3. 128g ÷ 128g/cup = 1 cup × 16 = 16.00 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 a Gram?

Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.

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.

Frequently Asked Questions

About 16.00 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.
Divide the grams by 128 (grams per cup) to get cups, then multiply by 16 to get tablespoons. For 128 grams: 128 ÷ 128 = 1 cups × 16 = 16.00 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: 16.00 tbsp ÷ 16 = 1 cups, then 1 × 128g/cup = 128g. Or use the Tablespoons to Grams converter.
