If you're looking to change the weather from Fahrenheit to Celsius on your watch, you're in the right place!
In order to do this, you'll need to change the language settings on your watch.
First, you'll need to access the settings on your watch. To do this, simply swipe down from the top of the clock face. This will bring up a menu with various options.
Next, you'll want to select 'Settings' from the menu.
Once you're in the settings menu, you'll need to select 'Language'. This will bring up a list of different languages that you can choose from.
Select 'English UK' if you want to use Celsius. This will change the language settings on your watch to display in UK English, which also uses the Celsius temperature scale.
Select 'English US' if you want to use Fahrenheit. This will change the language settings on your watch to display in US English regional settings like spelling and Fahrenheit temperature scale.
And that's it! You've successfully changed the weather display on your watch between Fahrenheit and Celsius. If you ever want to switch back, simply follow these steps again and select 'English US' or 'English UK' instead.
