How to scale a recipe
- Enter each ingredient as an amount and name, such as
2 cups flouror1 1/2 tsp salt. - Enter how many servings the recipe makes and how many you want, or a multiplier.
- Read the scaled amounts, with cooking-friendly fractions.
How it's calculated
Each ingredient line is parsed for a leading number (whole, decimal, a fraction like 1 1/2, or a Unicode fraction like 1½) — or a range like 2–3, where both ends scale — followed by the rest of the text unchanged. That number is multiplied by the scale factor — either target servings ÷ original servings, or your custom multiplier if you fill that in instead — and shown as a decimal plus the nearest common cooking fraction (to the nearest 1/8). Metric weights and volumes (g, kg, ml, l) are rounded to sensible whole or half numbers instead, since nobody weighs out 133 1/3 g. Lines without a leading number are copied through unscaled (like "salt to taste"). Nothing entered here is sent to a server.
Questions about scaling recipes
How do I halve a recipe?
Enter 0.5 as the multiplier, or set the servings to half. 1 1/2 cups becomes 3/4 cup.
Can it handle fractions and ranges?
Yes: 1 1/2, ½, decimals, and ranges such as 2–3, where both ends scale.
Are grams rounded?
Yes. Metric amounts are rounded to sensible whole or half numbers, as nobody weighs out 133⅓ g.
Do baking times change when I scale?
Often. Bigger or deeper tins need longer at a slightly lower temperature, so check early and test for doneness.
