Notes:
- FEPA: Federation of European Producers of Abrasives
- ANSI/CAMI: American National Standards Institute/Coated Abrasives Manufacturers Institute
- P prefix denotes European FEPA standard
- Micron values represent average particle diameter
- Higher numbers indicate finer abrasive particles and smoother surface finishing
- US standard is also commonly referred to as US Mesh
- Emery Grit uses a reverse scale where more zeros means finer particles
