Questions

Is 3.5 on a Timemore Sculptor 064 the same as 3.5 on a Timemore Chestnut C3?

No. The two grinders count in different steps, so the same number gives a different grind. 3.5 on the Timemore Sculptor 064 matches about 15 clicks on the Timemore Chestnut C3.

How accurate is this conversion?

It is a starting point. Both grinders are mapped to particle size in microns, fitted from the Honest Coffee Guide charts for each brew method, not from manufacturer burr-gap specs. Beans, roast and burr wear change the result, so adjust by taste.

The coffee tastes sour or bitter after converting. What should I change?

Sour and thin: grind finer by a step or two. Bitter and harsh: grind coarser. Change one thing at a time.
