Formula and Step-by-Step
- Start with 39.79 cups of all-purpose flour
- 1 cup of all-purpose flour = 125.16g
- 39.79 × 125.16 = 4,980.12g
- Convert grams to pounds: 4,980.12 ÷ 453.592 = 10.98 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?
The abbreviation "lb" comes from the Latin word "libra." One pound equals exactly 453.59237 grams. For rough mental math, 1 pound is slightly less than half a kilogram.
