How Much Is 20.42 Cups of Butter in Pounds?
20.42 cups of butter equals 10.22 lb. Butter has a density of 227g per cup (227g per cup), which means it's relatively heavy compared to other common cooking ingredients. For comparison, 20.42 cups of all-purpose flour would be 5.63 lb.
Formula and Step-by-Step
- Start with 20.42 cups of butter
- 1 cup of butter = 227g
- 20.42 × 227 = 4,635.34g
- Convert grams to pounds: 4,635.34 ÷ 453.592 = 10.22 lb
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Butter is easiest to measure using the markings on the wrapper. One US stick = 113g = 1/2 cup = 8 tablespoons.

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?
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.
