Formula and Step-by-Step
- Start with 2.91 cups of egg whites
- 1 cup of egg whites = 243g
- 2.91 × 243 = 707.13g

Measuring Tip
One large egg white weighs approximately 30g and one large egg yolk weighs approximately 17g. Weighing separated eggs is more reliable than counting, since individual eggs vary in size.
