Duck eggs vary, measure what you have
Chicken Egg to Duck Egg Conversion Calculator
Convert chicken eggs to duck eggs by edible weight, or work backward from the duck eggs you have, with practical advice for cakes, cookies, brownies, custards and quick breads.
Convert chicken eggs to duck eggs
Match edible egg weight without shells. Equal weight does not guarantee identical baking behavior. Defaults are arithmetic examples; weigh your eggs.
Enter decimals without thousands separators. Animal counts: 0-100,000; positive weights/rates: up to 10,000,000.
Whisk and weigh the target amount; refrigerate unused egg promptly. Follow your recipe’s cooking instructions.
Egg composition can change crumb, spread and rise. Use the recipe’s ratios and weigh carefully.
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.
How many chicken eggs equal one duck egg?
There is no universal fixed ratio because chicken and duck egg sizes vary. Match the edible weight for a more dependable substitution.
How much does a duck egg weigh?
Weigh the duck egg without its shell and enter that amount. Your measured egg is more useful for a recipe than one assumed average.
