When it comes to eggs, a common question arises: how many whole eggs are equivalent to a certain number of egg whites? This is a relevant query for those counting calories, monitoring cholesterol intake, or following specific recipes. Let's delve into this topic, providing a clear breakdown and useful conversions.
Understanding Egg Sizes and Weights
Before we dive into conversions, it's essential to understand that eggs come in various sizes, primarily ranging from peewee to jumbo. The most common sizes are medium, large, and extra large. For this discussion, we'll focus on these three sizes, as they are the most widely available and used in recipes.
Egg Sizes and Average Weights
- Medium: approximately 50g (1.75 oz)
- Large: approximately 60g (2.12 oz)
- Extra Large: approximately 70g (2.47 oz)
Egg Yolk and White Weights
The weight of an egg yolk and egg white can vary, but on average, they make up the following percentages of the whole egg's weight:

- Egg yolk: about 30% of the whole egg's weight
- Egg white: about 70% of the whole egg's weight
Calculating Egg Whites from Whole Eggs
Now, let's calculate how many whole eggs are equivalent to a certain number of egg whites, based on the average weights mentioned earlier.
Medium Eggs
If you're using medium eggs, one egg white weighs about 35g (1.23 oz). To find out how many whole eggs this is, we can set up a proportion:
1 egg white (70% of a medium egg) / 1 medium egg = 1 egg white / X whole eggs

Solving for X gives us approximately 1.43 whole eggs. So, one egg white from a medium egg is roughly equivalent to 1.43 whole eggs.
Large Eggs
For large eggs, one egg white weighs about 42g (1.48 oz). Using the same proportion as above:
1 egg white (70% of a large egg) / 1 large egg = 1 egg white / Y whole eggs
Solving for Y gives us approximately 1.29 whole eggs. Therefore, one egg white from a large egg is roughly equivalent to 1.29 whole eggs.
Extra Large Eggs
For extra large eggs, one egg white weighs about 49g (1.72 oz). Again, using the same proportion:
1 egg white (70% of an extra large egg) / 1 extra large egg = 1 egg white / Z whole eggs
Solving for Z gives us approximately 1.14 whole eggs. Thus, one egg white from an extra large egg is roughly equivalent to 1.14 whole eggs.
Summary Table
| Egg Size | Weight of One Egg White (g) | Equivalent Whole Eggs |
|---|---|---|
| Medium | 35 | 1.43 |
| Large | 42 | 1.29 |
| Extra Large | 49 | 1.14 |
In conclusion, the number of whole eggs equivalent to a certain number of egg whites depends on the size of the eggs. This guide provides a helpful reference for those looking to convert egg whites to whole eggs or vice versa.
