Heck, I've been in the coated abrasive business for 34 years and still find grit sizes confusing. If grit sizes can confuse those us who make our livelihood from it, well you know....

My grit chart comparing CAMI & FEPA is located at:

Grit Chart

Yes there are other grit sizes, but I very seldom run in to them.

Basically CAMI (USA) & FEPA (European) grits coarser than 240 are about the same, but finer grits do not compare at all grit size for grit size.

Most of our products are FEPA or "P" graded.

As for me when I sand a pen I typically start at P120 and go up to P400 then apply a CA finish.

Bye for now,
