How Much Is 3 Cups of Egg Whites in Pounds?
3 cups of egg whites equals 1.61 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, 3 cups of all-purpose flour would be 0.83 lb.
Formula and Step-by-Step
- Start with 3 cups of egg whites
- 1 cup of egg whites = 243g
- 3 × 243 = 729g
- Convert grams to pounds: 729 ÷ 453.592 = 1.61 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.

Understanding the Units
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
What is a Pound?
The abbreviation "lb" comes from the Latin word "libra." One pound equals exactly 453.59237 grams. For rough mental math, 1 pound is slightly less than half a kilogram.
