Example calculations

Family brunch
Scale a pancake batch from 4 to 10 servings
A simple case where volume units climb into larger kitchen-friendly measures instead of staying in teaspoons.
Result: Scale factor 2.5x with ingredient amounts normalized into cleaner kitchen units
Margarita pitcher (8 drinks)
Scale a single margarita to a party batch
Use Cocktail mode to see the total batch volume and an ice dilution estimate for shaken drinks.
Result: 36 oz batch before ice — expect ~43 oz total with dilution from shaking
Old Fashioned for 4
Batch a classic stirred cocktail
Stirred drinks dilute less than shaken — the dilution estimate gives a rough planning number.
Result: 9 oz batch with bitters — about 11 oz after dilution from stirring over ice
How the recipe scaler works
The calculator divides target servings by original servings to get a scale factor, then multiplies each ingredient by that factor so the recipe keeps its proportions.
After scaling, it normalizes the quantity within the same unit family when the result becomes easier to read in a larger or smaller kitchen measure.
Recipe-scaling FAQs
How serving-based scaling works, when units normalize, and why some ingredients still need judgment.
How does the scale factor work?
The scale factor is target servings divided by original servings. Every ingredient amount is multiplied by that same factor so the recipe keeps its proportions.
Why do some units change after scaling?
Because the calculator normalizes within the same measurement family to keep the result more readable. A large teaspoon amount may convert to tablespoons, and a large gram amount may convert to kilograms.
Does this solve kitchen judgment calls like eggs or seasoning by taste?
No. It handles arithmetic scaling only. For very large or very small batches, ingredients like eggs, leavening, salt, and spices still benefit from human judgment and recipe testing.
