How Much Is 0.66 Cups of Butter in Pounds?
0.66 cups of butter weighs 0.33 lb. This is based on butter having a density of 227g per cup. Because cups measure volume and pounds measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 0.66 cups.
Formula and Step-by-Step
- Start with 0.66 cups of butter
- 1 cup of butter = 227g
- 0.66 × 227 = 149.82g
- Convert grams to pounds: 149.82 ÷ 453.592 = 0.33 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.
