[routeconverter]

I've suggest RouteConverter to a gent from the U.S. who is asking for how to set up to get miles as he does not do metric <grin> so it is still coming up regularly to me. I've suggested he write in and ask as well.

Would that gent and you be willing to test for me, if it works and whether I've caught all places where lengths are displayed? My plan then would be to stay with metric values internally, offer an option to switch to miles and do the conversion on the view level.
