Countries using mile and not kilometer as unit of length

Lately I have continuously improved my latest Android app,
GPS Location Recorder. One feature with the app is to track the distance you are going/cycling/driving etc.

In the beginning I only supported meters/kilometers as unit of length as most countries use this unit.
