How Much Is 150 Grams of Cornstarch in Tablespoons?
150 grams of cornstarch equals 18.75 tbsp. Cornstarch has a density of 128g per cup. Because grams measure weight and tablespoons measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 150 grams of cornstarch
- 1 cup of cornstarch = 128g
- 150g ÷ 128g/cup = 1.17 cups × 16 = 18.75 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?
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.
