Formula and Step-by-Step

cups × 230g/cup ÷ 453.592g/lb = pounds
  1. Start with 3 cups of sour cream
  2. 1 cup of sour cream = 230g
  3. 3 × 230 = 690g
  4. Convert grams to pounds: 690 ÷ 453.592 = 1.52 lb

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

Measuring Tip

Thickness varies between brands. Full-fat, low-fat, and non-fat versions can have slightly different weights per measuring cup.

Frequently Asked Questions

About 1.52 lb, based on sour cream having a density of 230g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 230 (grams per cup for sour cream), then divide by 453.592 to convert grams to pounds. For 3 cups: 3 × 230 = 690g, then 690 ÷ 453.592 = 1.52 lb.
For the most accurate results, weigh sour cream 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: 1.52 lb × 453.592 = 690g, then 690g ÷ 230 = 3 cups. Or use the Pounds to Cups converter.
