Converting a setting
If a recipe quotes a setting for one of these grinders, read across for the equivalent on the other. Rows are spaced evenly by grind size, not by dial number — on a conical burr those are not the same thing.

Where the connectors bunch, that grinder’s dial is compressed and single steps count for more. Comparing the two shapes tells you which gives finer control, and where.

Dialing in the C40 MK4
The reference hand grinder for filter, and its click scale has become a de facto standard — plenty of published recipes quote "C40 clicks" as though it were a universal unit. It is not, which is the reason this site exists. The MK4 runs coarser than most people assume relative to electric grinders: if you are converting a recipe written for a Baratza, do not simply match the number.
Dialing in the M47 Classic
A heavy, precision-built hand grinder with stepless adjustment and genuine espresso capability. The lack of detents means repeatability depends on your own reference marks — the settings here are targets rather than clicks.
