I do I change the units from Km to miles?

I bought the s2 tonight and love it! However the running app all the units are in KM. How do I change it to miles? Like the distance tracker for example has units in kilometers instead of miles.

S health -> settings -> profile -> distance unit -> mi

Got it figured out. Why is it when I ran on the treadmill at the gym it wouldn't record any distance but when I did regular walking and ran outside it recorded distance fine? is it because I'm running in one place on the treadmill and something with the sensors in the watch?
