I don't know how "Grit" compares to "micron". (????)
If anyone has a chart/comparison, I would love to see it posted.
I'll give it a go:
180 grit = 80 micron
230 grit = 60 micron
280 grit = 45 micron
320 grit = 40 micron
360 grit = 35 micron
400 grit = 30 micron
500 grit = 20 micron
600 grit = 15 micron
900 grit = 12 micron
1200 grit = 9 micron
1500 grit = 5 micron
NOTE: There are slight variations in grit/micron conversions amoung different manufacturers of abrasive products. The properties I listed above will be very close for the most common seen in the US.
