Scale recipe ingredients to any number of servings
The recipe scaler turns original and desired servings into a scale factor: factor = desired servings รท original servings. You multiply every ingredient of your recipe by this factor; the calculator demonstrates it on an example list (500 g flour, 3 eggs, 250 ml milk, 100 g butter, 80 g sugar). Going from 4 to 6 servings gives a factor of 1.50, so 500 g flour becomes 750 g.

Divide every ingredient quantity by the same factor, for example halving each amount to make half a batch. Keep the oven temperature unchanged and shorten the baking or cooking time, since a smaller quantity in a smaller pan cooks faster.
A browser-based recipe scaler like this one works without any install: enter the original and the desired number of servings and it shows the scale factor, for example 1.50 when going from 4 to 6 servings. Multiply each ingredient of your recipe by that factor; the calculator demonstrates it on an example list. Many recipe and note apps offer a similar scaling feature.
It depends on the job. To change the number of servings you only need the scale factor, desired servings divided by original servings, which this recipe scaler calculates (4 to 6 servings gives 1.50). Converting cups to grams is a different task that needs ingredient-specific densities, because a cup of flour, sugar or butter weighs different amounts; this calculator does not do that.
The recipe scaler converts a recipe from the number of servings in the cookbook to the number you need. You enter just two numbers: Original Servings and Desired Servings. The calculator shows the scale factor and applies it to a fixed example list of five ingredients. You multiply the ingredients of your own recipe by the same factor.
| Ingredient | Original (4 servings) | 2 servings (0.50ร) | 6 servings (1.50ร) | 10 servings (2.50ร) |
|---|---|---|---|---|
| Flour | 500 g | 250 g | 750 g | 1,250 g |
| Eggs | 3 pcs | 2 pcs | 5 pcs | 8 pcs |
| Milk | 250 ml | 125 ml | 375 ml | 625 ml |
| Butter | 100 g | 50 g | 150 g | 250 g |
| Sugar | 80 g | 40 g | 120 g | 200 g |
Eggs are rounded: 1.5 eggs become 2, 4.5 become 5 and 7.5 become 8. From 4 to 7 servings (1.75ร), 250 ml milk becomes 437.5 ml, which the calculator rounds to 440 ml.
No. The calculator only asks for original and desired servings and shows the scale factor. You multiply each ingredient of your recipe by that factor yourself; the example list with flour, eggs, milk, butter and sugar shows what that looks like.
Piece counts are rounded to whole pieces: at 1.50ร, 3 eggs become 4.5 in theory and 5 are shown. Amounts of 100 or more are rounded to the nearest 5, amounts under 10 to one decimal.
No, it only scales by the factor. The unit of an ingredient stays the same, so at 1.50ร 2 cups become 3 cups.
