Questions people ask
What is P1200 in CAMI grit?
About 600. P1200 averages 15.3 microns on the FEPA table and CAMI 600 averages 16, so the scratch is close to the same.
How many microns is P1200 sandpaper?
About 15.3 microns average particle diameter, per the FEPA P-grade table (ISO 6344).
What Trizact grade is P1200?
3M pairs P1200 with Trizact A16 in its Trizact brochure. Don't read the A-number as microns: 3M's own pairings put A45 at P400, which averages 35 microns on the FEPA table.

Sizes are average particle diameters from the published FEPA (ISO 6344) and CAMI (ANSI B74.12/B74.18) tables. "Nearest" means within 10%; otherwise both neighbors are shown. Trizact pairings are 3M's own. Sources: Wikipedia, "Sandpaper" grit table (rev. 1127917881); Klingspor coated abrasives grit chart; 3M Trizact A-to-P table.
