This is super easy - go to our website www.scoutlookweather.com then log in by tapping Account in upper right corner of screen.
Then tap ACCOUNT tab from the drop down menu. On the next screen just scroll down and select UNIT PREFERENCE, then be sure to SAVE.
Give it a few minutes to work through our system and should work on website and app in metric units.
Thanks and good luck - and thanks for using Scoutlook!
