Convert percentage and CGPA
How to choose the correct formula
- Check your transcript, marksheet notes, academic regulations, examination-cell circular, or official conversion certificate.
- Match the grading scheme and year; rules can differ by program or regulation.
- If no rule exists, do not present a guessed multiplier as an official equivalent.
Under the ×9.5 rule, 77.9% maps to 8.2 CGPA. Under proportional ten-point scaling it maps to 7.79, which shows why the institution rule matters.
Frequently asked questions
Why are several formulas offered?
Different boards and universities use different mappings. A single multiplier cannot accurately represent all systems.
Can this create an official conversion certificate?
No. Only the relevant institution can issue or confirm an official equivalent CGPA or percentage.
Can I convert CGPA back to percentage?
Yes. Change the direction and use the same institution formula.
