Micron vs. Grit

[David G.]

I've been using a polishing kit that I purchased at my LHS. It contains six sheets that are similar in size and weight to dryer sheets. They are color coded and range from 30 micron down to 1 micron.

I've been using these for some time now and I'm pleased with the results I've obtained with them.

My question is:

How do "microns" compare to "grit"? The sheets are rated at 30, 15, 9, 3, 2, and 1 microns. What would be an equivalent grit rating for each of those sheets?

Thanks,

David G.
