I have no opposition to including the metric system, and especially in scientific articles. But in many articles, Americans will have a hard time understanding unless English equivalents are given.
I would certainly oppose any idea that the Metric system is better than English (it isn't, and for many purposes it's provably worse), and going further, even if Metric were better, it isn't the role of wikipedia to push it on people. (The government in the U.S. has been trying since I was a little kid to encourage the use of Metric, but with only tiny impact.)
So, I would say that in cases where Americans expect to see miles and gallons, we should give both miles/kilometers and gallons/liters.
And similarly, of course, in cases where Europeans and British and Aussies and others expect to see kilometers and liters, we should give those, as well.
