Changing Your Distance Display Units for Activity Tracking
The default unit for information about distance is miles. However, the ability to convert your data to kilometers (KM) was added with the release of Firmware 3.9.

To switch from miles to kilometers:
- launch the Pebble app
- go to Settings
- find the "Extended Settings" and tap "Unit Preference"
- select Kilometers
You can choose to revert back to miles at any time by following the same steps, but selecting Miles at the end.
If the "Extended Settings" option does not appear in the Settings of your Pebble app, please make sure that it and your watch are up to date.
- Click here to check the iTunes App Store for updates.
- Click here to check Google Play for updates.
- To make sure your watch is up to date, select Support in your Pebble mobile app. Then tap the "Update your Pebble" button.
