I personally like the metric system, and the imperial system. I did work with engineers from Russia and Romania and one of them asked me how in the world we could put up with fractional measurements. He said he had a hard time wrapping his head around it.
I guess it's whatever you grew up with. As far as I am concerned, numbers are numbers. The only problem is that most of us Yanks have to have a set of metric tools and a set of SAE tools. Is that true with Europe and Asia as well?
