How Much Is 22.58 Ounces of Cornstarch in Cups?
22.58 ounces of cornstarch equals 5.00 cups. That's 640.13g, 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 22.58 ounces of cornstarch
- Convert ounces to grams: 22.58 × 28.35 = 640.13g
- 1 cup of cornstarch = 128g
- 640.13g ÷ 128g/cup = 5.00 cups
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?
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?
The US cup (236.588 ml) is slightly smaller than the metric cup used in Australia and some other countries (250 ml). When following recipes from different countries, check which cup standard is being used.
