Converting 3 cups of egg whites to ounces gives 25.71 oz. One cup of egg whites weighs 243g, so 3 cups is 3 × 243 = 729g (25.71 oz). This conversion is specific to egg whites because each ingredient has a different density.
Formula and Step-by-Step
- Start with 3 cups of egg whites
- 1 cup of egg whites = 243g
- 3 × 243 = 729g
- Convert grams to ounces: 729 ÷ 28.3495 = 25.71 oz
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.

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 an Ounce?
An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
