During my apprenticeship worked both Imperial and metric, it was a long transition period when metric was introduced in Aus.
Then it was smooth sailing for ages with metric, until I joined my current company which is US owned, so now I work with imperial measurements, funny thing is I convert the imperial value in my head so I can visualise it in metric, I must be going nuts! :)
But the strangest thing is we receive 3D data from the US in metric, work that logic out!!
