To convert your CGPA on a 10.0 scale to a percentage, multiply your CGPA score by 9.5. The mathematical conversion formula is: Percentage (%) = CGPA × 9.5. For example, a 9.2 CGPA converts to 87.4% (9.2 × 9.5).
Why the 9.5 Factor is Used
Many academic boards, including India's CBSE and various global universities, use the 9.5 scaling coefficient. According to educational research on comparative scoring, the average score of top performers rarely hits 100% due to grading distributions. To normalize CGPA with actual marks percentages, boards analyzed previous scoring averages and mapped the 10-point scale to a maximum representative percentage using this coefficient.
You can find more detail on international standard scales on the Wikipedia Grading Systems Reference Guide.
