How can I switch from imperial to metric (or metric to imperial)?

The units shown by your Luxelion apps are controlled by your settings on the Garmin device.

On your watch, go to:

• Settings
• System
• Format
• Units
• Scroll down to change the metric of choice to your preferred unit.

As of LuxeLion Data Module ℹ️D6 (which launched March 28, 2023), It’s also possible to override this setting using the settings for your watch face.
