Apparently there is a book on how to convert crochet to knitting and vice versa, but honestly I think it's a rip off, since both methods are different. At least so different that I don't see an apparent way of interconverting them.
Each method has its strengths and weaknesses, that's why we learn both if we want to have the most flexibility.
The ways of Yarn are inscrutable.
