Fahrenheit (I even had to go and look up the spelling) has completely disappeared. I have absolutely no idea what the weather in Fahrenheit means other than doing some mental arithmetic.
I don't agree. I've found that us Brits tend to use Celsius for cold temperatures and Fahrenheit for warm when discussing the weather (a national past-time). So when its Winter we say its 2 degrees outside, but in the Summer we say wow its 90 degrees and people will know what the weather will feel like. If you told me it was 35 degrees C I would know it would be hot but not how hot. Equally, if you told me it was 20 degrees F I would know it was cold but not how cold.
