How Much Is 0.2 Cups of Cornstarch in Ounces?
0.2 cups of cornstarch equals 0.90 oz. Cornstarch has a density of 128g per cup (128g per cup), which means it's relatively light compared to other common cooking ingredients. For comparison, 0.2 cups of honey would be 2.40 oz.
Formula and Step-by-Step
- Start with 0.2 cups of cornstarch
- 1 cup of cornstarch = 128g
- 0.2 × 128 = 25.6g
- Convert grams to ounces: 25.6 ÷ 28.3495 = 0.90 oz
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.
