Recipe Scaling Calculator
Scale named ingredient quantities from original servings to target servings while preserving each entered unit label.
Formula
Scale factor = target servings / original servings; scaled ingredient = original amount x scale factor.
About the Recipe Scaling Calculator
Scale named ingredient quantities from original servings to target servings while preserving each entered unit label.
How the Recipe Scaling Calculator Works
Each ingredient line is parsed as name, numeric amount, and optional unit; every amount is multiplied by the same serving ratio and returned as a reusable list.
Formula
Scale factor = target servings / original servings; scaled ingredient = original amount x scale factor.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
Required Inputs
- Original servings (required).
- Target servings (required).
- Ingredients: name, amount, optional unit (required).
Results Reported

Accuracy and Limitations
Cooking time, pan area, seasoning, leavening, evaporation, egg count, and process limits may not scale linearly. Keep units separate when ingredients use different measures.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
