How coarse is that grit?
Average particle sizes from FEPA (ISO 6344), ANSI B74.12/B74.18 and JIS R6001. Brands and bonds vary; treat values between listed grits as estimates.
The math
How to convert grit to CAMI
Grit scales are tables: P220 = 68 µm = CAMI 220, but P1000 = 18.3 µm ≈ CAMI 600. Between listed grits the size is interpolated.
Example: P220 grit = 213 CAMI.
