Take a look at how i do it in tower-wear. This package contains all the code used to handle unit conversion.

That code depends on the library provided by this jar file.

I'm debating having this library included into the 3DR Services client library, and making it default. My thinking is that no all apps would need to convert units, so it would be a bloat for their use case.

I only display two units. Altitude in meters, and speed in m/s. I was thinking I would add a checkbox to the activity. If that checkbox is checked, then I would multiply these values by their respective magic numbers before forwarding them to the pebble.
