Well after around 20 years or so that I’ve known the idea of meassuring units, I have had no proplems with the practicality of the metric system nor I’ve ever heard anyone else here complaining it. After introducing myself to the engineering scenes and to the wonderfull world of AutoCad, I praise the Gods that we have 10-centric meassure systems were you can convert units by simply changing the dot…

Guess its just about how difficoult you wish to make your life :rolleyes: 😉

Therein lies the rub if you are not careful about where you put the dot or remember whether it’s supposed to be mm or cm. 12.7 mm = 0.5″ whereas 127mm or 12.7 cm = 5″ not a good idea to get it wrong as the parts don’t fit. Not that it bothers me anyway as I grew up with imperial measurements and spent (on and off) 14 years in Germany working with metric so I am at home with either but some people aren’t that lucky.
