Verified university option
The SPPU option uses the linked official conversion document and calculates Percentage = CGPA × 8.9. Select it only when SPPU’s rule applies to your marksheet and programme.

Three careful steps
The arithmetic is easy only after the correct institutional rule has been identified. Keep the source and calculation together, especially when an application asks for percentage.
Use the university or board that issued the marksheet. A college affiliated with a university normally follows the university’s published conversion rule unless its official document says otherwise.
Check the marksheet, transcript instructions, university examination page or an official conversion certificate. Do not copy a multiplier from an unrelated university or an old coaching article.
Select a verified formula when it applies. Otherwise choose Custom and enter the official multiplier only when the institution uses simple multiplication.
Read the visible working, follow the application’s rounding instruction and keep the official formula document available in case verification is requested.
Formula integrity
Universities may use a different multiplier, an offset, a grade-band table or a programme-specific rule. The correct percentage is the result of the rule that applies to your award—not the most common formula found online.
The SPPU option uses the linked official conversion document and calculates Percentage = CGPA × 8.9. Select it only when SPPU’s rule applies to your marksheet and programme.
Custom mode is for a multiplier printed by your own institution. It is not permission to guess 9.5 or another convenient number. If the rule includes subtraction, bands or different terms, follow that full rule outside this simple multiplier calculator.
The calculator shows a precise result, but an application may request two decimal places or another rounding method. Follow the form wording and never report a higher rounded value when the instruction requires truncation.
Percentage = CGPA × 8.9
SPPU official CGPA conversion formulaWorked examples
These examples demonstrate why the source matters. The second multiplier is illustrative and must not be used unless an institution actually publishes it.
| CGPA | Formula | Result | Use when |
|---|---|---|---|
| 7.50 | 7.50 × 8.9 | 66.75% | The verified SPPU rule applies. |
| 7.50 | 7.50 × 9.5 | 71.25% | Only an institution that officially publishes ×9.5. |
| 8.20 | 8.20 × 8.9 | 72.98% | The verified SPPU rule applies. |
A calculator cannot decide which formula governs your degree. Confirm that from the institution before using the result in recruitment or admission.
Clear answers
No. Institutions publish different conversion policies. Use ×9.5 only when your institution’s official rule explicitly uses it.
Do not force it into Custom multiplier. Apply the full published formula or obtain the official conversion certificate required by the application.
Only when the instruction asks for SGPA and provides an SGPA conversion rule. CGPA generally represents cumulative performance and should not be replaced by a single semester value.
No. The value and calculation remain in the browser and are not submitted to the site or added to analytics.
