P60 in CAMI grit and microns.

P60 paper averages about 269 µm on the FEPA table. On the US CAMI scale that is about CAMI 60. A sheet printed plain "60" is about 265 µm, close enough that the P barely matters at this grade.

Questions people ask

What is P60 in CAMI grit?

About 60. P60 averages 269 microns on the FEPA table and CAMI 60 averages 265, so the scratch is close to the same.

How many microns is P60 sandpaper?

About 269 microns average particle diameter, per the FEPA P-grade table (ISO 6344).

Is P60 the same as 60 grit?

Close enough to treat as the same. P60 averages 269 microns and CAMI 60 (a bare "60" on US paper) averages 265.

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.
