How Much Is 0.5 Cups of Egg Whites in Pounds?
0.5 cups of egg whites weighs 0.27 lb. This is based on egg whites having a density of 243g 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 0.5 cups.
Formula and Step-by-Step
- Start with 0.5 cups of egg whites
- 1 cup of egg whites = 243g
- 0.5 × 243 = 121.5g
- Convert grams to pounds: 121.5 ÷ 453.592 = 0.27 lb
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Carton egg whites and yolks have very consistent density, making them easier to measure by volume than freshly separated eggs. If your recipe calls for a specific gram amount, carton products are the most predictable.
