Is there a way to convert only part of a youtube file into an MP3 file?

Yes

Use Youtube Downloader

You download the video (the full thing) and then when you convert it to an mp3 (the program does both - download and convert), you can choose what time to what time you want. If a song is 4 minutes long and just want the last 2 minutes you'd type that in.

Try Nidesoft Youtube Video Converter!

1st of all you need to convert that video in an MP3 format...

Then, as you said you want just a part of it..

You'll need to download 1 more software called Mp3 to Ringtone converter ( also known as MP3RT ) which is available for free.. With the help of this software you can cut the song and get the part you want!!

u can try orbit downloader, I've been using it for a long time. it is able to save and download any streaming video from youtube,Google Video, Myspace, Metacafe, Dailymotion, iFilm, Music, eVideoShare, StreetFire, etc. off to your computer's hard drive free.

Your downloaded youtube vidoe is flv video, you just have to get a flv converter to extract music from flv video to mp3. and it support crop & trim the video into a desired area and size. I always use FLV to Video Converter to convert flv video to MP3,

I don't think so, I downloaded a few videos from youtube so I could use them in a powerpoint presentation and I never heard anything of it. I'm sure if you use it and claim it as your own then you might get in trouble.
