Formula and Step-by-Step
- Start with 2.66 cups of cornstarch
- 1 cup of cornstarch = 128g
- 2.66 × 128 = 340.48g
- Convert grams to pounds: 340.48 ÷ 453.592 = 0.75 lb
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 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.
What is a Pound?
Pounds are the standard weight unit for buying ingredients in the US. A standard bag of flour is 5 pounds (2,268g) and a standard bag of sugar is 4 pounds (1,814g).
