OK, this is a bit of surprise. This "X(v) / meters" obviously means "I want
the value in meters"?
Actually I spent quite some time trying to figure that exact thing out and
I just couldn't find it in the docs. I have just tried it and it works.
Great, that's at least a way to make things explicit and helps.
