So simple yet not working....

[giladal]

When execute your code, I get this:
Insert temperature: 35C
35
Insert temperature: 25f
25

So it appears it works, but the general approach is not that good.
What if user enters 27B?

Thank you very much Askic.

I haven't gotten to that yet. :)

That is very weird that it works for you and it doesn't work for me.
