Moka pot ratio calculator: what your pot actually gives you
Bialetti's instruction is volumetric, not a ratio. Weigh your funnel dose once and the calculator tells you the ratio your pot has been running all along.
The calculator above is the full coffee ratio calculator with moka pot loaded. Switch methods with the buttons at the top and your numbers convert with it.
The published starting points
These are starting points, not laws. Every figure below is quoted from the source named beside it, and the calculator flags you when your number falls outside the published band.
