What is a recipe scaling calculator?
It converts ingredient amounts when you want more or fewer servings than the original recipe.
How to scale a recipe
Enter original servings, desired servings, then add ingredients with quantities and units.
When this calculator is useful
Use it when cooking for a different group size, meal prepping, or reducing leftovers.
Practical guidance
What this tool does
This tool scales ingredient quantities from an original serving count to a desired serving count. It keeps the ingredient names and units you enter, then recalculates each quantity using the same serving ratio.
When to use it
Use it when doubling a recipe, cooking for fewer people or adjusting a meal plan before shopping.
Example use
If a recipe serves 4 and you need 6 servings, enter 4 as the original servings and 6 as the desired servings. A 200 g ingredient becomes 300 g because the scaling factor is 6 divided by 4.
How this tool works
For each ingredient, the calculator multiplies the original quantity by desired servings divided by original servings. The result is rounded for display and keeps the same unit, so you can review the updated ingredient table before cooking.
Limitations
The formula is proportional and may not handle every cooking detail. Spices, baking chemistry, yeast, thickening agents, pan size, oven time and rounding may need manual cooking judgment.

FAQ
What formula is used?
The calculator uses: new quantity equals original quantity times desired servings divided by original servings. It gives a practical scaling estimate, but you should still review taste-sensitive ingredients such as salt, spices, yeast, or thickening agents.
Can I copy results?
Yes. Use Copy results after calculating to copy the scaled ingredient list into your clipboard. It is useful when you want to paste the adjusted recipe into notes, a shopping list, or a message.
Are fractions supported?
Yes. Enter decimal values such as 0.5 or 1.25 when your ingredient amount is not a whole number. It is still worth checking the final kitchen-friendly amount yourself, especially for very small quantities or spices.
Are my recipes saved?
No. The tool runs in your browser and does not save recipes on a ToolForge Online server. If you need the adjusted recipe later, copy the results or print the page before leaving.
