Formula and Step-by-Step

cups × 227g/cup ÷ 453.592g/lb = pounds
  1. Start with 315 cups of butter
  2. 1 cup of butter = 227g
  3. 315 × 227 = 71,505g
  4. Convert grams to pounds: 71,505 ÷ 453.592 = 157.64 lb

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Softened butter and melted butter measure differently by volume. Melted butter settles with no air pockets, giving a slightly higher weight per cup.

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.

Frequently Asked Questions

About 157.64 lb, based on butter having a density of 227g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 227 (grams per cup for butter), then divide by 453.592 to convert grams to pounds. For 315 cups: 315 × 227 = 71,505g, then 71,505 ÷ 453.592 = 157.64 lb.
For the most accurate results, weigh butter on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
Fat content has a small effect on density. Higher-fat versions are slightly lighter per volume because fat is less dense than water. The difference is usually under 5%, so this conversion works well for standard varieties.
Reverse the conversion: 157.64 lb × 453.592 = 71,505g, then 71,505g ÷ 227 = 315 cups. Or use the Pounds to Cups converter.
