Cocktail batch calculator

It takes Number of servings and Volume per serving (ml) and derives Total volume (ml) and Total volume (litres) from them. The calculation is live as you type, so the result updates on every change.

2 values: Number of servings and Volume per serving (ml). Nothing else is required — no account, no file upload.

With Number of servings = 10 and Volume per serving (ml) = 120, the calculator returns Total volume (ml) = 1,200 and Total volume (litres) = 1.2. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

It moves a lot. Using Number of servings = 20 and Volume per serving (ml) = 132 instead, Total volume (ml) goes from 1,200 to 2,640 — which is why it is worth testing a few scenarios rather than trusting a single figure.

Scaled down to Number of servings = 5 and Volume per serving (ml) = 108, Total volume (ml) comes out at 540. 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 Total volume (litres); the Cocktail ABV calculator returns Final ABV and Standard drinks. That is the whole difference — open the one whose figure you need.

Cost per serving calculator is the closest one after this: Work out the cost of one serving from a recipe's total cost and number of servings.

Meat per person calculator and Catering cost calculator — they come up in the same task often enough to be worth a second tab.
