CGPA to Percentage Conversion
Converting CGPA to percentage is often required for job applications, higher education admissions, and official documentation. Different institutions use different formulas, so it's important to use the correct one.
Standard CGPA to Percentage Formulas
Generic Formula (Most Common)
Percentage = CGPA × 9.5
This is the most widely used formula, including by CBSE (Central Board of Secondary Education) in India.
Example:
- CGPA: 8.6
- Percentage: 8.6 × 9.5 = 81.7%
CBSE Official Formula
For CBSE board examinations:
Percentage = CGPA × 9.5
This formula is officially recognized and used in CBSE marksheets.
Alternative Formula
Some institutions use:
Percentage = (CGPA - 0.5) × 10
Example:
- CGPA: 8.6
- Percentage: (8.6 - 0.5) × 10 = 81%
University-Specific Formulas
| University/Board | Formula | Example (CGPA 8.5) |
|---|---|---|
| CBSE | CGPA × 9.5 | 80.75% |
| Anna University | CGPA × 10 | 85% |
| Mumbai University | (CGPA - 0.5) × 10 | 80% |
| VTU | CGPA × 10 | 85% |
| GTU | CGPA × 9.5 | 80.75% |
SGPA to Percentage Conversion
SGPA (Semester Grade Point Average) converts to percentage using the same formulas:
Percentage = SGPA × 9.5
Percentage to CGPA Conversion
To reverse the conversion:
CGPA = Percentage / 9.5
Example:
- Percentage: 85%
- CGPA: 85 / 9.5 = 8.95
Why Different Formulas Exist
Different formulas exist because:
- Grade Distribution: Some systems have different grade boundaries
- Historical Practices: Universities developed their own standards
- Academic Rigor: Some institutions weight grades differently
- Regional Standards: Different countries have different norms
