How Much Is 5.01 Ounces of Cornstarch in Cups?
5.01 ounces of cornstarch equals 1.11 cups. That's 142.03g, and Cornstarch has a density of 128g per cup. Because ounces measure weight and cups measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 5.01 ounces of cornstarch
- Convert ounces to grams: 5.01 × 28.35 = 142.03g
- 1 cup of cornstarch = 128g
- 142.03g ÷ 128g/cup = 1.11 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.
