How Much Is 5 Ounces of Cornstarch in Cups?
Converting 5 ounces of cornstarch to cups gives 1.11 cups. First convert to grams (5 oz = 141.75g), 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 5 ounces of cornstarch
- Convert ounces to grams: 5 × 28.35 = 141.75g
- 1 cup of cornstarch = 128g
- 141.75g ÷ 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
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?
Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.
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.
