How Much Is 3.03 Ounces of Cornstarch in Cups?
Converting 3.03 ounces of cornstarch to cups gives 0.67 cups. First convert to grams (3.03 oz = 85.90g), 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 3.03 ounces of cornstarch
- Convert ounces to grams: 3.03 × 28.35 = 85.90g
- 1 cup of cornstarch = 128g
- 85.90g ÷ 128g/cup = 0.67 cups
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 an Ounce?
An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
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.
