A large portion of the easily accessable internet does seem to be very US based.. or atleast the sites i use.
Admittedly i get weather from the local news sites.. which are well local, so local wording (Danish) and temps.
The lack of consistency isnt helping either
TVs, Monitors, Phone Screens and all other kinds of displays are measured diagonally... in inches (Translated terms do exist, Danish is "Tomme/r" in fact). but Hardware temps (CPU GPU etc) are in Celsius.
Atleast they are basically international in that case (Anyone measure their CPU temps in Fahrenheit?) but its still a bit weird.
It works the same way. The actual formula is: F = C * 1.8000 + 32.00
