How Much Is 0.89 Cups of Cornstarch in Ounces?
Converting 0.89 cups of cornstarch to ounces gives 4.02 oz. One cup of cornstarch weighs 128g, so 0.89 cups is 0.89 × 128 = 113.92g (4.02 oz). This conversion is specific to cornstarch because each ingredient has a different density.
Formula and Step-by-Step
- Start with 0.89 cups of cornstarch
- 1 cup of cornstarch = 128g
- 0.89 × 128 = 113.92g
- Convert grams to ounces: 113.92 ÷ 28.3495 = 4.02 oz
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 Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
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.
