How to use it
- Enter ingredients (one per line), original servings and servings you need.
- The result appears straight away and updates as you edit.
- Copy the result, or copy a link that keeps the same values to share it.
How it is calculated
Factor = new servings ÷ original servings; each new quantity = original quantity × factor, rounded to 2 decimals.
Example
Inputs: Original servings = 4, Servings you need = 10. Result: Scaling factor: 2.5; Lines scaled: 4.
500 g lamb 2 cups basmati rice 1/4 tsp saffron 1 onion
1250 g lamb 5 cups basmati rice 0.63 tsp saffron 2.5 onion
Limits and caveats
- Only the quantity at the start of a line is scaled; numbers mid-sentence and numbered method steps stay as they are.
- Spices, salt and yeast do not always scale linearly, so taste and adjust.
- Cooking time and pot size do not scale by the same factor.
