How Much Is 5 Pounds of Cornstarch in Cups?
Converting 5 pounds of cornstarch to cups gives 17.72 cups. First convert to grams (5 lb = 2,267.96g), 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 pounds of cornstarch
- Convert pounds to grams: 5 × 453.59 = 2,267.96g
- 1 cup of cornstarch = 128g
- 2,267.96g ÷ 128g/cup = 17.72 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Humidity affects cornstarch weight. In humid conditions, flour absorbs moisture and weighs more per cup. Store it in an airtight container for consistent results.

Understanding the Units
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).
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.
