Formula and Step-by-Step
- Start with 0.64 cups of cornstarch
- 1 cup of cornstarch = 128g
- 0.64 × 128 = 81.92g
- Convert grams to ounces: 81.92 ÷ 28.3495 = 2.89 oz
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.
