Recipe Scaler
Paste a recipe and change the servings — each ingredient quantity is scaled, fractions and all.
Scale any recipe up or down
Doubling a recipe or cooking for a different number of people means recalculating every quantity — a chore that invites mistakes. This scaler reads the amount at the start of each ingredient line and multiplies it by the ratio of your new servings to the old, keeping the units and ingredient names exactly as written.
It understands the messy ways recipes write numbers: whole numbers, decimals, plain fractions like 1/2, and mixed numbers like 1 1/2. Scaling four servings up to six, for instance, turns "2 cups flour" into "3 cups flour" and "1 1/2 tsp salt" into "2 1/4 tsp salt".
Amounts only, kept private
It scales quantities but does not convert units, since volume-to-weight depends on the ingredient. Everything runs in your browser and nothing you paste is uploaded.
Frequently Asked Questions
How does the recipe scaler work?
It finds the quantity at the start of each ingredient line and multiplies it by the ratio of your desired servings to the original, leaving the units and ingredient names untouched.
Does it understand fractions?
Yes. It reads whole numbers, decimals, fractions like 1/2, and mixed numbers like 1 1/2, and returns tidy results (halves, thirds, and quarters where they fit).
Will it convert cups to grams?
No — it scales the amount but keeps your original units. Volume-to-weight depends on the ingredient, so unit conversion is a separate job.
Is my recipe uploaded?
No. The scaling runs in your browser and nothing you paste is sent anywhere.
