> Out of genuine curiosity, what's the advantage from your point of view, other than being able to communicate to other people who use the same system, at the cost of not being understood by everyone else?

What other advantage, you ask? Well, I'd say that there is none. I was merely trying to convey that being fluent in both imperial and metric is better than being fluent in only metric. As long as it doesn't hurt me (which imperial doesn't) the more skill-sets I have, the better!

I hope you better see where I'm coming from now. You didn't work me up though, and I also didn't mean to work anyone up either. :)
