It was not difficult for me, as you have probably noticed before.
I know & accept we live in the metric age.That will not change.
But all of my thinking , Lathe, Mill, Stock, Micrometers, Verniers Dial Gauges, Sine Bars, Everything is Imperial. Everything:U
When you blokes talk .05mm etc my brain is immediately converting to "meaningful" Imperial.
Not a problem, except when it comes to Screw Threads. One has to carry Metric Taps & Dies, Imperial...BA, UNC, Brass, BSW, BSF, Model Engineers, & so the story goes on, together with No Drills, Letter drills, Fraction Drills, Metric Drills & so the story goes on.
However as Andre says its good to have tools on hand.:2tsup:
