How Much Is 3 Tablespoons of Cornstarch in Grams?

3 tablespoons of cornstarch weighs 24.00 g. This is based on cornstarch having a density of 128g per cup. Because tablespoons measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 3 tablespoons.

Formula and Step-by-Step

tablespoons × 8g/tbsp = grams
  1. Start with 3 tablespoons of cornstarch
  2. 1 tablespoon of cornstarch = 8g
  3. 3 × 8 = 24g

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?

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.

What is a Gram?

A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.

Frequently Asked Questions

About 24.00 g, 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). For 3 tablespoons: 3 × 8 = 24.00 g.
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: 24.00 g ÷ 8 = 3 tablespoons. Or use the Grams to Tablespoons converter.
