How Much Is 1 Cup of Egg Whites in Pounds?
1 cup of egg whites equals 0.54 lb. Egg whites has a density of 243g per cup (243g per cup), which means it's relatively heavy compared to other common cooking ingredients. For comparison, 1 cup of all-purpose flour would be 0.28 lb.
Formula and Step-by-Step
- Start with 1 cup of egg whites
- 1 cup of egg whites = 243g
- 1 × 243 = 243g
- Convert grams to pounds: 243 ÷ 453.592 = 0.54 lb
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
A whole large egg without shell weighs about 50g. When separating eggs for a recipe, weigh the whites and yolks individually for the most accurate results.
