Grind setting conversion
Mahlkönig EK43 vs Weber EG-1
Two grinders cross-shopped at the same money. The EG-1 turns 0–10 rotations; the EK43 is numbered 0–16.
| EK43 | EG-1 | |
|---|---|---|
| Brand | Mahlkönig | Weber |
| Scale | Numbered dial | Rotations |
| Dial range | 0 – 16 | 0.0 rotations – 10.0 rotations |
| Burrs | Flat | Flat |
| Espresso → filter | 7 numbers | 3.5 rotations |
| Filter → coarse | 7 numbers | 4 rotations |
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.

Side by side, by brew method
Where each grinder lands for the same brew, worked out from its own dial curve.

|---|---|---|
| Espresso | 3.7 | 0.9 rotations |
| Moka pot | 7 | 1.8 rotations |
| AeroPress (short steep) | 7.8 | 2.7 rotations |
| Pour over — V60 / cone | 8.8 | 3.8 rotations |
| Pour over — flat bottom | 9.8 | 4.3 rotations |
| Drip / batch brew | 10.7 | 4.7 rotations |
| Chemex | 12 | 5.2 rotations |
| French press | 14.1 | 6.1 rotations |
| Cold brew | 15.2 | 7.2 rotations |
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.
Mahlkönig EK43
Weber EG-1
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.
Dialing in the EG-1
A single-dose grinder built to an extreme standard, with burr options that change its character substantially. Stepless and calibrated by the owner rather than the factory, so published numbers from other EG-1 users are a starting region rather than a setting.
