Drinks & coffee

Brewing ratios, beverages, and drink quantities.

Choose the tool whose inputs and output match your task. Check each calculator’s assumptions and limitations before using its result.

Latest update:

These tools turn drink recipes into repeatable ratios. If you know the final cup size you want, start with the coffee ratio calculator, which works backward from brewed volume to the starting water and ground coffee for French press, V60, Chemex, moka pot, cold brew, or espresso. When you already know one amount and just need its match, the coffee to water ratio calculator solves the other side of the same ratio, with regular and strong presets per method. For the rest of the kitchen, the rice water ratio calculator gives water, cooking time, and prep notes for rice types from jasmine to brown.

Frequently asked questions

What does the coffee ratio calculator measure?
It starts with the final drink volume you want and estimates the starting water and ground coffee needed for the selected brewing method. The result also includes a suggested grind size, water temperature, and brew time so the dose can be repeated instead of guessed each morning.
Why is the starting water more than the final coffee volume?
Most brewing methods leave some water behind in coffee grounds, paper filters, or the brewer itself. The calculator uses a water-loss percentage for each method, then works backward so a 250 ml target ends with about 250 ml in the cup rather than 250 ml poured at the start.
Are these ratios the only correct way to brew coffee?
No. They are practical starting ratios, not universal rules. Roast level, grind quality, water chemistry, brew temperature, and taste preference all matter. Once the calculator gives a baseline, adjust one variable at a time and write down the result that tastes best to you.
