Odometer in kilometers

Jenn and I took this afternoon off and I decided my arm was healed enough (it’s been over three weeks now since I got an avulsion fracture in my elbow, or not, depending on which doctor I believe) to ride our scooters downtown. We went to the BodyWorlds3 show at OMSI and then had dinner at Piazza Italia.
We’d noticed her LXV150′s odometer was really racking up the miles. But after comparing our route home according to Google and the mileage on both of our odometers…she’s actually really racking up the kilometers. Presumably there’s a little knob somewhere inside the console that needs twiddled.
