One of the most searched academic questions in India is "how to convert CGPA to percentage" — and the honest answer is that it depends on your university, because there is no single formula mandated across all institutions.
The Most Commonly Cited General Formula
The AICTE-referenced approximation used by many universities is:
Percentage = (CGPA − 0.75) × 10
Example: a CGPA of 8.5 → (8.5 − 0.75) × 10 = 77.5%
An Alternative Formula Used by Some Universities
Percentage = CGPA × 9.5
Example: a CGPA of 8.5 → 8.5 × 9.5 = 80.75%
Notice these two formulas give meaningfully different results for the same CGPA — which is exactly why you must confirm which one your specific university uses before quoting a percentage on an application or resume.
Why the Formula Differs
Each university calibrates its own grade-point-to-marks mapping when it designs its grading policy. Since the underlying marks distribution behind each grade point differs slightly by institution, the "correct" multiplier is technically an institution-specific approximation, not a universal mathematical fact.
How to Find Your University's Official Formula
- Check your official transcript/marksheet — some universities print both CGPA and the equivalent percentage directly
- Check your university's examination or academic regulations document (usually available on the official website)
- Ask your department's examination cell directly if it isn't published
When You Actually Need a Precise Conversion
For most job applications, stating your CGPA directly is acceptable and increasingly preferred over a converted percentage. Precise conversion matters most for: higher education applications abroad (some universities require a percentage equivalent), specific government exam eligibility criteria, and scholarship applications that specify a percentage cutoff.
