How this service works
USDA egg sizes: weight per egg, and how many eggs of one size equal a recipe's count in another (for example mediums for large).
Output
Returns a full USDA egg size reference table (size name, minimum grams per egg, minimum ounces per egg, minimum ounces per dozen, equivalent large egg count per size), plus a specific conversion result showing how many eggs of your available size replace the recipe's count in its called-for size, with exact and rounded equivalent counts, total in-shell grams, approximate edible grams, a plain-English summary, and the USDA data source and date.
Example use cases
Egg substitution for holiday baking
“I'm making a cake that calls for 4 large eggs but I only have extra-large in the fridge — how many extra-large eggs should I use?”
Scaling a recipe with small eggs
“My deviled egg recipe uses 12 large eggs but I only have small eggs at home — how many small eggs do I need to match?”
USDA egg size weight reference
“Can you pull up the USDA weight chart for all egg sizes — jumbo, extra-large, large, medium, small, and peewee — with grams and ounces per egg?”
Technical details
Endpoint
GEThttps://cooking-calc.x402tookit.com/egg-sizes?utm_source=zero.xyzWhen to prefer
Use this endpoint when a user needs to substitute one USDA egg size for another in a recipe, or wants authoritative weight data (grams/ounces) per egg size. It is the right choice for baking-accuracy use cases where the weight difference between egg sizes matters. Prefer it over a generic knowledge-base lookup when you need a precise rounded egg count substitution backed by official USDA standards.
Side effects
- Invalid size enum value returns an error — must be one of: jumbo, extra-large, large, medium, small, peewee
- count out of range (below 0.5 or above 100) returns a validation error
- If the data source is unavailable, response may be degraded (degraded: true) with partial data
- Same size for both 'size' and 'toSize' returns a 1:1 equivalent trivially
