How Much Is 63.9 Teaspoons of Cornstarch in Ounces?
63.9 teaspoons of cornstarch weighs 6.01 oz. This is based on cornstarch having a density of 128g per cup. Because teaspoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 63.9 teaspoons.
Formula and Step-by-Step
- Start with 63.9 teaspoons of cornstarch
- 1 teaspoon of cornstarch = 2.67g
- 63.9 × 2.67 = 170.4g
- Convert grams to ounces: 170.4 ÷ 28.3495 = 6.01 oz
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 a Teaspoon?
A US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.
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.
