Difference between "translated" to and "translate into"

Hi guys!

I was talking about the importance of learning English, when I got questions about the ways to use verb translate. I was wondering, is there any difference between "translate to" and "translate into"? I'm very confused with this :S

The sentence I want to write is:

Learn other languages are very useful when a lot of books, hqs and series that you like usually aren't translated to/into your native language.

Thanks in advenced!
