Who built KitchenYield
KitchenYield is an independent kitchen-calculator project designed to make common recipe, pan, and oven conversions easier to check before ingredients go in the bowl.
Pan-size conversions
For rectangular pans, we calculate base area as length × width. For round pans, we use π × radius². The recipe multiplier is the target pan area divided by the original pan area.
Area is a useful starting point, not a guarantee of identical baking. Batter depth, pan material, oven behavior, recipe density, and headroom can change the result. We call out these limits rather than treating a pan swap as exact science.
Recipe scaling
The scaler multiplies each entered quantity by the selected factor or by target servings ÷ original servings. It displays familiar fractions where a result is close to one, otherwise it keeps up to two decimal places.
Eggs, leavening, salt, spices, and very small measurements need human judgment. For fractional eggs, beat the egg first and measure by weight or volume. The calculator does not silently alter a recipe formula.
Oven temperatures
Celsius, Fahrenheit, and Gas Mark values are converted using standard temperature relationships and then rounded to practical household-oven settings. Fan-oven guidance is a starting adjustment, not a substitute for checking the food.
Domestic ovens can run hot or cool, and browning also changes with rack position, pan colour, airflow, sugar content, and recipe type. Use the recipe’s stated doneness cues whenever possible.
Ingredient weights and density
Cup-to-gram conversions are ingredient-specific: a cup measures volume, while grams measure mass. Flour, butter, sugar, cocoa, and liquids do not share the same density, and packed versus spooned ingredients can differ too.
When KitchenYield publishes an ingredient weight, the page will identify the ingredient form and cite its reference source. We prefer manufacturer specifications, established baking-reference weights, and public food-composition data; a kitchen scale remains the most reproducible method.
Accuracy and corrections
KitchenYield is a planning aid, not a substitute for recipe testing or food-safety guidance. If a result looks wrong, use the recipe’s own instructions and your observed doneness cues. The calculators and guides are updated as methods and references are reviewed.
