Hi

If you would like to covert your CGPA into percentage for that you need to multiply your GPA with 9.5 then you will get your percentage i.e percentage =GPA multiplied by 9.5 . Actually this GPA is introduced because to avoid feeling of losing top ranks because of 1-2marks difference GPA is introduced and the Person who got 10 gpa outoff 10 gpa may score percentage between 95% and 100% so that's the reason we will multiple by 9.5

Hope this information is helpful

ALL the best
