Scrolling Is Evil / Tomato Potato
Recipe scaler: change servings
Paste the ingredients, enter the servings you want, and every amount is rescaled. Cups and spoons come back as measures you can fill, so 0.125 cup reads 2 tbsp and 0.33 cup reads 5 tbsp + 1 tsp. This free scaler runs in your browser and sends nothing anywhere.

In Tomato Potato, each recipe's servings scale its own shopping lines.
How it works
- Paste the ingredients, one per line. Amounts such as 2 cups, 1 1/2 tsp or ½ lb are read, and a line like For the sauce: stays as a heading.
- Enter the servings the recipe makes. A line such as Serves 6 on its own line in the paste is used when the field is empty, and with neither the page assumes 4.
- Enter the servings you want, or tap ×½, ×2 or ×3.
- Every amount is multiplied by the same ratio. Cups, tablespoons and teaspoons come back as measures you can fill. Pounds, ounces and cans keep their unit and show fractions, and grams and millilitres keep theirs.
- Eggs, garlic cloves and packs such as cans that land on part of one get a short note. Lines with no amount, like salt and pepper to taste, are copied as they are.
- Tap Copy list or Print list, or make a grocery list from the result.
Questions
How do I halve or double a recipe?
Paste the ingredients and tap ×½ to halve them or ×2 to double them. ×3 triples them. For any other size, enter the servings the recipe makes and the servings you want, and every amount is multiplied by the same ratio.
Why does 0.33 cup turn into spoons?
A scaled amount helps only if you can measure it. Under a tablespoon it stays in teaspoons with fractions, like 1½ tsp, and under 1/16 tsp it reads a pinch. Up to a cup, an amount that lands on ¼, ⅓, ½, ⅔ or ¾ cup stays in cups, and anything else becomes tablespoons and teaspoons: 0.125 cup is 2 tbsp, and 0.33 cup is 5 tbsp + 1 tsp. Past half a cup it rounds to the nearest tablespoon, and from 4 cups up to the nearest cup fraction.
What happens to an egg when I halve a recipe?
A counted item that lands on part of one keeps its fraction. One egg at half the recipe reads ½ egg, with a note to beat an egg and measure out the part you need. A large egg is about 3 tbsp. Cloves, cans, jars, bags and other packs get a short note too. An onion or a potato is just ½.
Does it convert grams, ounces or pounds?
It scales them and keeps the unit you pasted, so 1½ lb stays pounds and 250 g stays grams. Grams and millilitres print as whole numbers from 10 up and one decimal below. Only cups, tablespoons and teaspoons are converted into each other.
What if the recipe does not say how many it serves?
Enter the number in the servings field. If you leave it empty, the page uses a line such as Serves 6 on its own line in your paste, and 4 when there is none.
Does it change cooking time or pan size?
No. Only the ingredient amounts change. A different batch size often needs a different pan and cooking time, and you set those yourself.
Is it free, and is anything saved?
It is free. The ingredients are scaled inside your browser, never sent anywhere, and not stored.
Can I turn the scaled recipe into a shopping list?
Yes. Tap Make a grocery list from this under the result. The grocery list tool opens with the scaled ingredients already in its box, sorted by aisle.
