Recipe Serving Scaler

How this tool works

Enter original and desired serving counts, then add each ingredient as amount, unit and name separated by vertical bars. Amounts accept decimals and fractions such as 1/2 or 1 1/2. Every amount is multiplied by desired servings divided by original servings. Units remain unchanged, so this is not a density conversion. Cooking time, pan size and seasoning do not always scale linearly. Review fractional eggs and very small measures before preparing the recipe, and follow appropriate food-safety instructions.

How do I get a useful result?

Start by reading the field labels and the method above. Replace the example values with information that matches your own situation, then use the main button to generate the result. Review the units, dates and any assumptions before copying or printing it. If you change an input, run the tool again so the output reflects your latest choices. An example is a starting point for learning the controls, not a recommendation for your circumstances.

Does this page upload my information?

This tool performs its work in your browser. Its input values are not submitted to a server by the calculator. Closing or reloading the page clears unsaved work. Checklist pages offer an explicit browser-save option; that storage belongs to this browser and device and may be cleared by private browsing or browser settings. Downloads, printed pages and copied text contain whatever information you included, so keep them somewhere appropriate.

Can I use it on a phone?

The form and result panels adapt to a smaller screen. Use your device’s normal keyboard to enter values, and review the output before sharing it. The print button opens the browser’s print controls, where available. Printing and saving as PDF depend on your operating system. If a feature is unavailable, try a current browser with JavaScript enabled. Keep a separate copy of anything important; the page is not a cloud backup service.
