Formula and Step-by-Step

cups × 227g/cup ÷ 453.592g/lb = pounds
  1. Start with 6.64 cups of butter
  2. 1 cup of butter = 227g
  3. 6.64 × 227 = 1,507.28g
  4. Convert grams to pounds: 1,507.28 ÷ 453.592 = 3.32 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.

Frequently Asked Questions

About 3.32 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 6.64 cups: 6.64 × 227 = 1,507.28g, then 1,507.28 ÷ 453.592 = 3.32 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: 3.32 lb × 453.592 = 1,507.28g, then 1,507.28g ÷ 227 = 6.64 cups. Or use the Pounds to Cups converter.
