Coffee calculator: ratio, dose and grind size
Work out how much water or coffee you need for espresso, moka pot, V60 or French press, and the grind size in microns and in clicks of your grinder.
Coffee and water
Pick a method or type your ratio (grams of water per gram of coffee).
For 15 g of coffee: 240 g of water.
For 500 g of water: 31.3 g of coffee.
Grind size
Approximate particle size per method and, if you know your grinder's microns per click, how many clicks to start at.
Between 450 and 750 microns.
A starting point, not a rule: bitter means coarser, sour or weak means finer. Log it in “My coffee”.
This coffee bar runs on coffee… literally. And the odd ko‑fi.
