Quick answer
To convert CGPA to percentage, multiply your CGPA by 9.5 (the most common formula, used by CBSE and many Indian universities): Percentage = CGPA × 9.5. Example: 8.5 × 9.5 = 80.75%. To go the other way, divide: CGPA = Percentage ÷ 9.5. Use the calculator below — it converts both ways as you type, and you can change the multiplier to match your university.
Convert CGPA to percentage
Enter your CGPA to get the percentage, or type a percentage to get the CGPA. Set the multiplier your university uses (9.5 is the default).

Not sure of your multiplier? Check your university's grading rules on your result or academic handbook. When in doubt, 9.5 is the most widely used.
The CGPA to percentage formula
Most Indian universities and boards convert on a 10-point scale using a single multiplier:
Percentage = CGPA × 9.5
This ×9.5 rule was popularised by the CBSE and is now the default at many institutions. To reverse it, simply divide: CGPA = Percentage ÷ 9.5.
Worked example
Suppose your CGPA is 8.5 and your university uses the ×9.5 formula:
- CGPA: 8.5
- Multiplier: 9.5
- Calculation: 8.5 × 9.5 = 80.75%
Going the other way, a percentage of 80.75 ÷ 9.5 = 8.5 CGPA. The calculator does this rounding for you automatically.
University multipliers & formulas
The ×9.5 rule is common but not universal. Always confirm your institution's method — here are the patterns you'll see:
| Method | Formula | Used by (typical) |
|---|---|---|
| ×9.5 | Percentage = CGPA × 9.5 | CBSE & many Indian universities |
| ×10 | Percentage = CGPA × 10 | Some universities & autonomous colleges |
| Subtract-and-multiply | Percentage = (CGPA − 0.75) × 10 | e.g. some state universities |
| Grade-point specific | Institution's own conversion table | Universities with custom scales |
This tool is a personal aid. Your university's official conversion is always the source of truth — use its stated multiplier or table for anything official like job or higher-study applications.
SGPA, CGPA and percentage — what's the difference?
- SGPA (Semester Grade Point Average) is your average for a single semester.
- CGPA (Cumulative GPA) is the average across all completed semesters.
- Percentage is CGPA (or SGPA) converted using your university's multiplier.
To turn SGPA into a percentage, use the same formula: SGPA × 9.5. To find CGPA from multiple SGPAs, average them (weighted by credits if your university requires it), then convert.
