About the Recipe Scaler
Resize a recipe for more or fewer people. Enter how many servings the recipe makes and how many you need, paste the ingredients one per line, and the scaler multiplies the amount each line starts with, such as 2 eggs or 1½ cups, written as 2, 1½, 3/4 or 0.75.
How to use it
- 1 Enter the Original servings the recipe makes.
- 2 Enter the Desired servings you want to cook.
- 3 Paste the Ingredients, one per line, with the amount first, for example 2 cups flour, 1½ tsp salt or 2 eggs.
- 4 Read the Scaling factor, then the new amounts under Scaled recipe.
Frequently asked questions
Desired servings divided by original servings. Scaling a 4-serving recipe to 8 servings gives a factor of 2, so each scaled amount doubles; 4 to 2 servings gives 0.5 and halves it.
Cups, tablespoons (tbsp), teaspoons (tsp), pounds (lb), ounces (oz), grams (g), kilograms (kg), milliliters or millilitres (ml) and liters or litres (l), each as a whole word, so the 4 in 4 lengths is not read as 4 liters. The amount a line starts with is scaled with or without a unit, so 2 eggs doubles to 4 eggs. A later amount on the line, as in 2 cups (250 g) flour, is scaled when one of these units comes straight after it.
No, only how many you need. A size in brackets between the count and a container, as in 1 (14 oz) can, or after an x, as in 1 x 400g tin, describes each package, so doubled they read 2 (14 oz) cans and 2 x 400g tins. Containers are cans, tins, jars, packages, packets, packs, bags, boxes, bottles, cartons, sticks and envelopes. A bracketed amount anywhere else, as in 2 cups (250 g) flour, is a measurement and scales.
As kitchen fractions such as 1/3, 1/2 or 3/4 when the result is close to one, so 1 cup scaled by 0.5 reads 1/2 cup and 3 tsp scaled by 1.5 reads 4½ tsp. Anything else is rounded to two decimal places. A unit or container after the amount follows it, so 1 cup doubled reads 2 cups and 2 cans halved reads 1 can.
No. It only scales ingredient amounts. A bigger batch may need a larger pan and a longer cooking time, and the Baking Pan Converter can help you pick the pan.
