How Much Is 2.23 Ounces of Egg Whites in Cups?
2.23 ounces of egg whites equals 0.26 cups. Egg whites has a density of 243g per cup. A lighter ingredient like flour (125g/cup) would fill more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 2.23 ounces of egg whites
- Convert ounces to grams: 2.23 × 28.35 = 63.22g
- 1 cup of egg whites = 243g
- 63.22g ÷ 243g/cup = 0.26 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
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.

Understanding the Units
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.
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.
