How Much Is 8 Ounces of Egg Whites in Cups?
Converting 8 ounces of egg whites to cups gives 0.93 cups. First convert to grams (8 oz = 226.80g), then divide by the density of egg whites (243g per cup). Each ingredient fills a different volume at the same weight.
Formula and Step-by-Step
- Start with 8 ounces of egg whites
- Convert ounces to grams: 8 × 28.35 = 226.80g
- 1 cup of egg whites = 243g
- 226.80g ÷ 243g/cup = 0.93 cups
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 an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
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.
