How Much Is 3 Ounces of Cornstarch in Tablespoons?
Converting 3 ounces of cornstarch to tablespoons gives 10.63 tbsp. First convert to grams (3 oz = 85.05g), then divide by the density of cornstarch (128g per cup). Each ingredient fills a different volume at the same weight.
Formula and Step-by-Step
- Start with 3 ounces of cornstarch
- Convert ounces to grams: 3 × 28.35 = 85.05g
- 1 cup of cornstarch = 128g
- 85.05g ÷ 128g/cup = 0.66 cups × 16 = 10.63 tablespoons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Different flour types have very different weights per cup. Always check the specific flour your recipe calls for rather than using a generic "flour" conversion.

Understanding the Units
What is an Ounce?
Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.
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.
