Halving a recipe can leave an instruction such as one and a half eggs. The Whatson Egg Portion Converter expresses that quantity as an edible mass using a reference you enter.
It offers whole egg, white and yolk as separate options. Shell mass is outside the calculation.
Select the portion before entering the amount
Choose whole egg, white or yolk, then decide whether your known amount is a count or a mass in grams. Only the selected portion’s reference mass is used.
The starting references are 50 g whole egg, 33 g white and 17 g yolk. They are editable illustrative masses, not a grading standard for eggs bought in Pakistan.
Use a measured reference that represents your recipe if a precise quantity matters. The tool cannot infer edible mass from shell colour, a market price or an egg size description.
One and a half whole eggs at the example reference
With whole egg selected and a 50 g edible reference, enter a count of 1.5 or 1 1/2. The checked result is 75 g edible whole egg.
The tool reports two whole reference portions to obtain that amount. That ceiling is an acquisition count: it does not mean two full eggs belong in the recipe instead of the calculated 75 g.
Starting from grams reverses the question
In grams mode, 75 g divided by the same 50 g reference gives 1.5 whole egg portions. For whites at a 33 g reference, 66 g corresponds to two reference whites.
The white and yolk references are independent entries. They are not required to add up to your selected whole egg reference, so check the mass you actually intend to use rather than treating the example numbers as a product analysis.
A mass conversion does not choose an egg substitute
The converter does not decide whether white can replace whole egg, or whether a yolk change preserves the recipe. It also does not supply preparation, storage or food safety instructions.
Recipe Scaler can generate a fractional count when resizing a recipe. Bring that count here only after deciding which edible portion the recipe requires.
For an ingredient cost, Recipe Cost Calculator can allocate a compatible piece quantity to a purchased pack of eggs. A gram based egg cost needs a compatible gram based pack quantity; the cost tool does not infer a grams per egg conversion.
Write the edible reference mass beside any converted amount. A note of “75 g using 50 g per whole egg” makes the calculation clear without implying every egg weighs the same.
