CGPA ↔ Percentage Converter
Convert between CGPA (10-point scale) and percentage using the widely used ×9.5 formula — with a note on why your institution's exact formula may differ.
CGPA → Percentage
Percentage → CGPA
Where the ×9.5 formula comes from
CBSE has used this formula to help students estimate an equivalent percentage from their 10-point CGPA for situations like job or admission applications that ask for a percentage. It's a linear approximation, not a precise measurement — two students with the same CGPA but different underlying marks would get the same converted percentage, which is one reason many institutions prefer official transcripts over converted figures.
When to use an official conversion instead
- Formal applications (further education, government jobs, visa applications) often require an official conversion certificate from your board or university, not a self-calculated one
- Some universities use a different multiplier or a non-linear scale — check your institution's own guidance
- This tool is best used for quick personal estimates, not as a substitute for official documentation
Frequently asked questions
What is the formula to convert CGPA to percentage?
The commonly cited formula (used by CBSE for its 10-point scale) is Percentage = CGPA × 9.5. For example, a CGPA of 8.4 converts to 8.4 × 9.5 = 79.8%.
Does every university use the ×9.5 formula?
No — this is the formula CBSE has publicized for its own scale. Many universities, especially outside CBSE, use their own conversion method or a different multiplier, and some require an official conversion certificate rather than a self-calculated figure.
How do I convert percentage back to CGPA?
Divide the percentage by 9.5 — for example, 79.8% ÷ 9.5 = 8.4 CGPA. Use the second calculator above for this direction.
Can I use this converted percentage for a job application?
Many employers and institutions accept a reasonable estimate, but for formal processes (higher education admissions, government jobs, visas) check whether they require an official conversion certificate from your board or university instead.
