How Much Is 0.21 Pounds of Cornstarch in Cups?
Converting 0.21 pounds of cornstarch to cups gives 0.74 cups. First convert to grams (0.21 lb = 95.25g), 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 0.21 pounds of cornstarch
- Convert pounds to grams: 0.21 × 453.59 = 95.25g
- 1 cup of cornstarch = 128g
- 95.25g ÷ 128g/cup = 0.74 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 a Pound?
A pound (lb) is a US customary unit of weight equal to 453.592 grams or 16 ounces. It is used for larger quantities of ingredients like flour, sugar, and meat.
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.
