About the GPA / CGPA Converter
Converts between a 10-point CGPA, a percentage score, and the US 4.0 GPA scale, using the conversion formulas most commonly cited by universities and credential-reference sites — distinct from this site's GPA Calculator, which computes a weighted 4.0-scale GPA from a list of letter-grade courses.
- Choose which score you have: CGPA, percentage, or 4.0 GPA.
- Enter that score.
- Read the equivalent values on the other two scales.
A CGPA of 8.2 converts to about 77.9% and a 3.28 GPA on the 4.0 scale. A 90% score converts to about 9.47 CGPA and a 3.6 GPA.
| CGPA | Percentage | GPA (4.0 scale) |
|---|---|---|
| 10.0 | 95.0% | 4.00 |
| 9.0 | 85.5% | 3.60 |
| 8.0 | 76.0% | 3.20 |
| 7.0 | 66.5% | 2.80 |
| 6.0 | 57.0% | 2.40 |
| 5.0 | 47.5% | 2.00 |
There is no single official, universally used formula for converting between these three scales — different universities, boards, and countries define their own rules. For an official conversion needed for a transcript, visa, or job application, check with your specific institution's registrar or use a formal credential evaluation service such as WES.
- • These formulas are independent approximations, not one internally consistent system.
- • The CGPA × 9.5 rule is the CBSE (India) convention; other boards may use a different multiplier.
- • If you're applying abroad, ask the receiving institution which conversion method they use.
