What weights are used for each egg size?

The values are per-egg equivalents of USDA minimum dozen weights for shell eggs: small about 43 g, medium 50 g, large 57 g, extra-large 64 g, and jumbo 71 g. They include the shell and are size-class references, not guaranteed weights for each individual egg.

Does the shell weight matter?

Yes when exact edible weight matters. This tool uses USDA shell-egg size ratios as a practical substitution estimate; for precision baking, crack the eggs and weigh the liquid egg required by the recipe.

What if the result is not a whole number?

The tool rounds to the nearest whole egg and shows the volume variance so you can decide whether to add or omit the partial egg. For most recipes a variance under 10% is negligible.

Are large eggs the standard for recipes?

Yes. Most American recipes are developed using large eggs. The 57 g shown here is the shell-egg size reference; edible contents are typically lighter.

Can I convert for baking and cooking equally?

Yes, though baking is more sensitive to small differences. For baked goods with many eggs, consider splitting the difference (e.g., use one more egg if variance is positive).

Summary

The Egg Size Converter helps you swap between small, medium, large, extra-large, and jumbo eggs in any recipe. It uses per-egg equivalents of USDA shell-egg weight classes (small 43 g, medium 50 g, large 57 g, extra-large 64 g, jumbo 71 g) to estimate substitutions. Results include both a whole-egg count and a practical note when rounding introduces a small variance.
