As far as I understand, every institution has its own formula for the conversion of CGPA to percentage. Hence, the following only applies to those students who have completed their undergraduate/postgraduate/etc., level of education from Banaras Hindu University.
BHU uses the following formula for conversion of Cumulative Grade Point Average (CGPA) to its equivalent percentage:
Percentage = (10 * CGPA) - 4.5
