It's a bit rough

After much lurking, finally a question…

a definative list of how various grades of emery paper (and there
seems to be at least two systems of measurement in the piles of stuff
I have) fit in with carborundum paper grades?

My emery stocks (some quite old!) have both alpha and alpha-numeric
coding, whilst here we have “wet-or-dry"paper in grades from 180 to
1500…(yep, I understand what that means)…then we go on with

Look forward to some informed replies…
