The US has the widest range of temperatures of any country. Locations can vary by >50°C in a 24 hour period. Extreme temperatures are familiar to Americans and their society is well-adapted to it.
Calling Fahrenheit "western centric" is nonsensical. Every other country has a narrower temperature range that fits within the US temperature range.

I assure you it does not. But I guess American Exceptionalism makes you want to believe that so go ahead.
A 5s google search suggests the country with the widest range is probably Russia.
