The same number means different things
Both grinders use a clicks, which makes it tempting to copy a number straight across. Setting 45 clicks sits at grind index 5.5 on the K6 but 30.9 on the Chestnut S3 — far enough apart to change the cup.
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.
KINGrinder K6
Timemore Chestnut S3
Dialing in the K6
KINGrinder's all-rounder, and the value benchmark hand grinders get measured against. External adjustment, 60 clicks a rotation, at 16 microns a click — a coarser step than the 1Zpresso J and X series manage, and the one place you feel the price: espresso is dialable, but in slightly bigger jumps than a stepless grinder gives you. The 48mm stainless heptagonal burrs are what separate it from the rest of the KINGrinder line. If you only ever pull shots, the K4 is the espresso-specific sibling with titanium-coated burrs; the K6 is the one that covers pour over through espresso without being built for either.
Dialing in the Chestnut S3
Sits above the C-series with better burrs and a more solid feel. Its useful range genuinely extends further toward espresso than the C3, though a dedicated espresso grinder will still out-resolve it.
