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.

The shape of each dial
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.
1Zpresso ZP6 Special
Kinu M47 Classic
Dialing in the ZP6 Special
Purpose-built for filter, with burrs cut to reduce fines rather than to cover espresso. It will not pull a shot and does not pretend to — inside its range it is one of the most uniform hand grinders available.
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.
