Here`s a formulae: http://en.wikipedia.org/wiki/Fahrenheit
I can`t calculate it right now, cause I have to go.
I should be back in like one hour.
You could calculate it for me if you want ;)
Idk but a friend of mine told me that it was 28 degree hot on friday!
But today it was also sunny.
Then it rained a lil bit...then it wasn`t that hot and the day already turned into night :D
