Formula and Step-by-Step
- Start with 0.81 cups of butter
- 1 cup of butter = 227g
- 0.81 × 227 = 183.87g
- Convert grams to pounds: 183.87 ÷ 453.592 = 0.41 lb
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Cold butter straight from the fridge is hardest to measure by volume. Cut it into tablespoon-sized pieces using the wrapper markings for accuracy.

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.
