Questions people actually ask
- How do I change temperature to Celsius?
- Settings, then General, then Language and Region, and set the temperature unit.
If it is not working
- Changing the system language restarts the interface and takes a minute.
- Temperature unit and first day of the week can be set independently of region on recent releases.
- Region affects some feature availability, so changing it to unlock a feature can break others.
