P220 in CAMI grit and microns.
P220 paper averages about 68 µm on the FEPA table. On the US CAMI scale that is about CAMI 220. A sheet printed plain "220" is about 68 µm, close enough that the P barely matters at this grade.

Questions people ask
What is P220 in CAMI grit?
About 220. P220 averages 68 microns on the FEPA table and CAMI 220 averages 68, so the scratch is close to the same.
How many microns is P220 sandpaper?
About 68 microns average particle diameter, per the FEPA P-grade table (ISO 6344).
Is P220 the same as 220 grit?
Close enough to treat as the same. P220 averages 68 microns and CAMI 220 (a bare "220" on US paper) averages 68.
What Trizact grade is P220?
3M pairs P220 with Trizact A90 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.
