About this calculator
Change a recipe from one number of servings to another. Paste the ingredients one per line with the amount first, and every amount is scaled for you, including fractions such as 1/2 and 1 1/2.
How it works
- The scale is the servings you want divided by the servings the recipe makes.
- The amount at the start of each line (a whole number, decimal, fraction or mixed number) is multiplied by that scale and shown as a simple fraction when it is close to one.
- Lines that do not start with an amount are left as they are.
Common questions
Do spices and salt scale in a straight line?
Not always. Strong spices, salt, baking powder and cooking times may need less than a straight multiple. Taste and adjust.
Will it change units, such as cups to litres?
No. It scales the amount and keeps your unit. Use the unit converter if you need to change units.
