How to Convert CGPA to Percentage
CGPA (Cumulative Grade Point Average) is an average of grade points, so it has to be converted with a formula. For the common 10-point scale used by CBSE, multiply your CGPA by 9.5.
Example: a CGPA of 8.2 gives 8.2 × 9.5 = 77.9%. CBSE does not print a percentage on the marksheet, so this result is an indicative percentage.
For a scale other than 10 points, divide your CGPA by the maximum of the scale and multiply by 100. For example, 3.2 out of 4 is (3.2 ÷ 4) × 100 = 80%.
CGPA to Percentage Formulas
There is no single universal formula. Boards and universities publish their own, so always use the one your institution or the receiving institution asks for.
| Method | Formula | Typically used for |
|---|---|---|
| CBSE | CGPA × 9.5 | CBSE 10-point CGPA (indicative percentage) |
| Simple | CGPA × 10 | Some 10-point university systems |
| VTU | (CGPA − 0.75) × 10 | Visvesvaraya Technological University |
| Proportional | (CGPA ÷ scale) × 100 | 4-point, 5-point or 7-point scales |
