Hi Ravi

To tell you something, there is no defined formulae to convert CGPA to percentage. It is important for you to know that eligibility varies from PSUs to PSUs and that's how some will ask to convert your CGPA to percentage but the matter of fact is that this conversion can be done taking help from the university you have appeared in your qualifying exam.

I hope this helps you.

All the best!

Actually the university will have given the parameters or methodology to convert. It is generally mentioned by the University. If not, you could ask the college authorities to give you the methodology. You should not calculate it on a generally based formula that someone may tell you. Pls ask the University for the same if you have no idea. Generally these things are mentioned by the university in the certificates issued to the students. so check that or like I said get in touch with the college authorities.
