FAQ
How is CGPA converted to percentage?
Using the CBSE formula: percentage = CGPA × 9.5. This is the standard multiplier used by CBSE and most Indian boards — if your institution uses a different formula, check your board's official conversion instead.
Does this work for any board, or just CBSE?
The CGPA-to-percentage field specifically uses the CBSE ×9.5 formula. Marks-to-percentage (obtained ÷ total) works for any board or exam, since that's a plain calculation with no board-specific rule.
Is this an official conversion for my transcript?
No — it's for quick reference. For an official gradesheet, always use the percentage or CGPA your board/university issues, since some institutions round differently or apply their own multiplier.
