Well, I think it's best just to get used to it. I recall a carpenter on one project who would use his conversion calculator to convert metric to Imperial and then measure off distances using his tape measure, which was graduated in Imperial AND metric. Jaysus, what a waste ! When I showed him that he could forget the calculator and just use his "hand held manual metric-Imperial linear measurement conversion device" he was a bit pissed, but found it worked just as well. Thirty two pounds equals one slug... aaarrrrggggghhhhhh !
