Formula and Step-by-Step

cups × 227g/cup ÷ 453.592g/lb = pounds
  1. Start with 351 cups of butter
  2. 1 cup of butter = 227g

  4. Convert grams to pounds: 79,677 ÷ 453.592 = 175.66 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.

Frequently Asked Questions

About 175.66 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 351 cups: 351 × 227 = 79,677g, then 79,677 ÷ 453.592 = 175.66 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: 175.66 lb × 453.592 = 79,677g, then 79,677g ÷ 227 = 351 cups. Or use the Pounds to Cups converter.
