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.

Dialing in the Mignon Libra

The Mignon with an integrated scale, grinding by weight rather than time. The dial behaves like the rest of the Mignon range; what changes is dose repeatability, not grind character.

Dialing in the EK43

The grinder that changed what filter coffee was supposed to taste like, and still the reference for high-clarity brewing. Its very large flat burrs produce an unusually narrow particle distribution, which is why coffee ground on an EK often tastes cleaner at the same nominal setting than it does elsewhere. Stepless, so treat the numbers as targets.
