Grit to Micron Comparison Chart
There are many ways to measure the individual particles that are embedded in abrasives. And because manufacturers differ slightly in their measuring systems, and particle shapes vary so much, it's nearly impossible to offer a standard comparison between grit sizes and micron sizes.
There are, however, some good estimations that will help you determine which abrasive to use. NOTE: This chart is an approximation and is for comparison only; measurements will vary from one manufacturer to another.
30 microns = approx. 400-grit
15 microns = approx. 600-grit
9 microns = approx. 1200-grit
3 microns = approx. 4000-grit
2 microns = approx. 6000-grit
1 microns = approx. 8000-grit
