CGPA

Percentage

Grade band
A2 / Excellent
Multiplying by 9.5 converts between the two, so a CGPA of 8.50 is 80.75%.
The CBSE × 9.5 rule comes from averaging the mid-point of each grade band across five years of results. It is an approximation, and different universities use different formulas — always use the one printed on your own marksheet or in your institution rules, because admissions offices will.
Frequently Asked Questions
How do I convert CGPA to percentage?
For CBSE, multiply your CGPA by 9.5. A CGPA of 8.5 becomes 80.75%. Other universities use different multipliers, and some use a formula with an added constant.
Where does the 9.5 multiplier come from?
CBSE derived it by averaging the mid-point of each grade band across five years of results. It is an approximation adopted for convenience, not an exact mathematical conversion.
Does every university use 9.5?
No. VTU, Anna University, Mumbai University and others each publish their own formula — Mumbai uses CGPA × 7.1 + 11. Always use the one printed on your marksheet, because that is what admissions offices and employers will apply.
Is CGPA or percentage better for applications?
Report whatever your marksheet states, and provide the official conversion formula alongside it if a form demands a percentage. Converting with the wrong multiplier can misrepresent your result either way.
