I'm using calibre to convert my books from pdf to mobi. My issue is that I have hundreds of books that are already in the mobi format and I'm looking only to convert the books that aren't already in the mobi format.
When I try to convert all of my books it converts the pdf books into mobi even if they are already in mobi. To convert my book collection is going to take many hours, and I'm wondering if there is a way to mass convert books that aren't already in the output format.
Thank you. Will accept any work around that accomplishes this.

I'm surprised nobody has responded in six months, sorry I haven't been here :-(
I do this all the time.
You want to convert everything that has formats:"=PDF" and doesn't have formats:"=MOBI". You can just put those conditions in the search box, or in the tag browser:
Select the PDF format (which will place a big + beside it), then
ctrl-select the MOBI format twice, instead of a + there'll be a -
You'll see the following selection string in the search box: not formats:"=MOBI" or formats:"=PDF". Now you have all the books that are either not MOBI or are PDF. That's not nearly what you want, but now just change the or to and (or delete it—no conjunction is the same as using and) in the search box and you have all of the PDFs that don't also have a MOBI.
