Recipe scaler

It takes Original servings, Desired servings and Ingredient amount and derives Scaled amount and Scaling factor from them. The calculation is live as you type, so the result updates on every change.

3 values: Original servings, Desired servings and Ingredient amount. Nothing else is required — no account, no file upload.

With Original servings = 4, Desired servings = 6 and Ingredient amount = 200, the calculator returns Scaled amount = 300 and Scaling factor = 1.5. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

It moves a lot. Using Original servings = 8, Desired servings = 12 and Ingredient amount = 400 instead, Scaled amount goes from 300 to 600 — which is why it is worth testing a few scenarios rather than trusting a single figure.

Scaled down to Original servings = 2, Desired servings = 3 and Ingredient amount = 100, Scaled amount comes out at 150. The relationship is worth checking at both ends before you rely on a single result.

Cooking from a recipe that does not match your kitchen: scaling for a different number of people, converting cups to grams, and substituting what you do not have.

Converting a cup as if it were a volume of weight. A cup of flour and a cup of sugar differ by nearly a third in mass, so a single conversion factor gets one of them badly wrong.

This one returns Scaled amount and Scaling factor; the Dietary Restriction Recipe Filter returns Result. That is the whole difference — open the one whose figure you need.

Cake Servings Calculator and Cocktail batch calculator — they come up in the same task often enough to be worth a second tab.
