On Fahrenheit, the Americans are surely right. For describing the weather, a system where the usual range is 30-100 is clearly more useful than one where it's 0-37, because you can say "high 70s" instead of the weirdly specific "about 27", and "low 40s" instead of the awkward "around 5 to 7".
I say this as a European who has never used Fahrenheit.
Around here, temperatures range from -40ºC to +40ºC. The most important information temperature offers is whether it is going to snow or rain. 0ºC being roughly the temperature where that transition happens makes thinking about it seem more natural than picking a random number out of the 30-100 scale (well, -40-+104).
