Recipe Converter & Scaler
Scale a recipe up or down to any number of servings.
Scaling factor: ×1.5
Scales each ingredient by the serving ratio, keeping units and rounding to friendly fractions (½, ¾…). Lines without a leading number pass through unchanged. Cooking times and pan sizes don't scale linearly — adjust those by eye. Runs in your browser.
Scale any recipe to the number of servings you need. Enter the original and desired servings, paste your ingredient list (one per line, quantity first), and every amount is multiplied by the right factor and rounded to friendly fractions like ½ and ¾. Lines without a number pass through untouched. Runs in your browser.

Frequently asked questions
Does it handle fractions like 1 1/2 cups?
Yes. It understands whole numbers, decimals, fractions (3/4), mixed numbers (1 1/2) and unicode fractions (½), and rounds results to the nearest friendly cooking fraction.
Does it scale cooking times too?
No — and you shouldn't scale times linearly. Doubling a recipe rarely doubles the cook time; adjust temperature and time by eye and check doneness.
