Falls Du nach den USA schreibst, die 50 Grad C. bitte in Fahrenheit umrechnen.

It can get as hot as 50° C.

"Can get" does not refer to "sein".

? but to "kann werden"

In your translation you have used "rise" and "temperature", neither of which are in the original sentence.

I was providing an authentic and colloquial BE translation, Werner. Please do not lecture me on how to speak my own language.

tomtom, please lecture me in interpreting my own language.

Werner, I side with tomtom on this one. What he says conveys the same information as the German (at least to native English speakers), even if it is not a one-to-one translation. Believe it or not, some of us native speakers of English can (most often) ACTUALLY understand what the German is saying, and we do have an idea of how that is ACTUALLY said in English!

Auch Unterstützung für tomtom, der das 'kann bis zu ... werden' (siehe Betreffzeile) völlig korrekt übersetzt hat und dies auch noch in bold hätte setzen können, sollen, dürfen.

It can get up to 122 degrees today
We could see temperatures/temps (as high as) in the 120s today.

Shame that Werner won't come back to this thread, or even if he does won't admit to having been wrong.

I also agree with tomtom.

I am not addicted to LEO and thus come back only occasionally. No, I do not admit to anything here.

Another vote for tomtom uk's version.

@Werner: a little humility wouldn't occasionally go amiss
