Hi,
if you use the international ADVS version, there should be an optioin at start, that you can set ot be shown in the management tools, that allows you to switch between EN (metric) and US(imperial) version. Otherwise there are both settings in the management tools and in the start/settings/ project settings tab to define the units that you want to use.
