So after many pages of a recent thread, which I posted in, I have set a New Decades Resolution to convert to using m(&)m's.
In this process, I have started buying a few, right now, fairly cheap measuring tools, Starrett stuff will come later (I hope).
One nice surprise today was a pair of Shinwa Stainless steel, non glare, rulers. I bought a 300mm ($11) and 600mm ruler ($25). One nice feature was that they both had all sorts of conversion information laser etched on the back side of the rulers.
