How the egg conversion works

The target is the total edible weight of the chicken eggs in the original recipe. A USDA large chicken egg is a useful 50-gram starting point without shell, but recipe labels and real eggs vary. We divide that target by the measured average weight of your shelled duck eggs.

For structure-sensitive recipes, crack and whisk the duck egg, then weigh only the amount needed. The calculator does not claim that egg weight is the only difference between species.
