Ingredients
Scaled recipe
How to use
- Enter the original servings of your recipe and the servings you want.
- Add each ingredient with its amount, unit, and name. The unit picker covers US and metric units, or leave the unit blank for countable items like eggs.
- The scaled amounts appear instantly — 16 tablespoons become 1 cup, 1000 milliliters become 1 liter, and 0.5 shows as 1/2.
- Copy the scaled recipe to your clipboard or print it for the kitchen.
Tip: volume and weight ingredients scale cleanly, but always taste and adjust seasoning — flavors do not always scale perfectly.
Frequently Asked Questions (FAQ)
How do I scale a recipe up or down?
Enter the original servings and the servings you want, then add each ingredient with its amount, unit, and name. Every amount is multiplied by the scale factor automatically.
What is the scale factor?
The scale factor is desired servings divided by original servings. For example, going from 4 to 8 servings gives a factor of 2, so every ingredient amount is doubled.
Does it convert units automatically?
Yes. Smart conversion turns values like 16 tablespoons into 1 cup, 1000 milliliters into 1 liter, and 16 ounces into 1 pound.
Can I use both US and metric units?
Yes. The unit picker includes teaspoons, tablespoons, fluid ounces, cups, pints, quarts, gallons, milliliters, liters, ounces, pounds, grams, and kilograms.
How are fractions displayed?
Amounts are shown in kitchen-friendly fractions. For example, 0.5 shows as 1/2, 1.5 as 1 1/2, and 0.25 as 1/4.
Can I copy or print the scaled recipe?
Yes. Use the Copy scaled recipe button to copy everything to your clipboard, or the Print button for a paper copy.
