Both grinders are mapped to one particle-size scale, fitted from the Honest Coffee Guide's per-method charts. It is not manufacturer burr-gap data, so treat this as a starting point and adjust by taste.

Questions

Is 1.5.1 on a 1Zpresso X-Ultra the same as 1.5.1 on a Option-O Lagom P64?

No. The two grinders count in different steps, so the same number gives a different grind. 1.5.1 on the 1Zpresso X-Ultra matches about 3.2 on the Option-O Lagom P64.

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.
