yep i don´t understand F as well ... Celsius rulez even so Kelvin is the only real unit ....

so i got abou 303 K ( 30 C) and for Berlin that´s quite a lot. but i don´t care about it much, because heat doesn´t bother me a all (as long as it is not humit), and 30 is not 46
and, i am at work, and so i just work slower ...
