How to use this tool
Scale line-by-line ingredient quantities from original to target servings and export the list.
Multiply each ingredient by target servings divided by original servings. This does not convert units or guarantee taste or baking outcomes.
💡 3 Quick Steps to Get Started
Enter positive original and target servings, for example4 and10.
Enter name,quantity,unit on each line with commas, such as Flour,200,g. Names and units cannot contain commas; quantities cannot be negative.
Calculate to obtain500 g of flour in this example, then inspect the result or download CSV.
When it helps
Adjust home recipes, party batches, and meal-prep quantities.
How it works
Multiplier = target servings ÷ original servings; each line quantity is multiplied and rounded to two decimals.
Worked example
Example: 200 g flour for 4 servings becomes 500 g for 10 servings.
Limits and data handling
Out-of-range servings, rows without exactly three fields, blank fields, or invalid quantities produce no result. Seasoning, cooking time, and cookware capacity may not scale linearly and still need judgment.
Servings, ingredient rows, scaled results, and the CSV are processed or generated only in your current browser. Recipe content is not sent to the GoGo Tools backend.

FAQ
Recipe scaler: How should I format the ingredient list?
Original and target servings must be from 1 to 100,000. Each nonblank line must contain ingredient,quantity,unit with a quantity of zero or more. The limit is 1,000 lines and 500 characters per line.
Recipe scaler: How is each ingredient quantity scaled?
The multiplier is target servings divided by original servings. Each original quantity is multiplied and rounded to two decimals; the screen shows scaled amounts, and the CSV keeps both original and scaled quantities.
Recipe scaler: Which errors or practical limits should I consider?
Out-of-range servings, rows without exactly three fields, blank fields, or invalid quantities produce no result. Seasoning, cooking time, and cookware capacity may not scale linearly and still need judgment.
