Questions people ask
What is P1500 in CAMI grit?
About 800. P1500 averages 12.6 microns on the FEPA table and CAMI 800 averages 12.6, so the scratch is close to the same.
How many microns is P1500 sandpaper?
About 12.6 microns average particle diameter, per the FEPA P-grade table (ISO 6344).
Convert any other grade, from CAMI, microns or a Trizact A-number, on the grit converter.
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.
