For CBSE, multiply your CGPA by 9.5 to get an indicative percentage: a CGPA of 8.6 is 81.7%. Using a university with a different rule? Enter its multiplier, or switch to percentage to CGPA to go the other way.
The formula
CGPA to percentage
percentage = CGPA × multiplierPercentage to CGPA
CGPA = percentage ÷ multiplierCBSE
multiplier = 9.5CBSE's circulars give the overall indicative percentage as 9.5 × CGPA; see for example its performance profile circular. Other boards and universities set their own.
Worked example
And backwards: 81.7% ÷ 9.5 = 8.6. With a university multiplier of 10, a CGPA of 7.5 is 75%, and a percentage of 82.5% is a CGPA of 8.25.
When to use it, and the mistakes to avoid
Use it for applications, forms and resumes that ask for a percentage when your result is a CGPA, and to find the CGPA a target percentage needs.
- Using 10 for CBSE. CBSE's multiplier is 9.5.
- Using a CBSE multiplier for a university. Each university has its own rule.
- Treating the result as official. It is an indicative figure unless your institution says otherwise.
- Converting a percentage above 95% to CBSE CGPA. A 10 CGPA is the top, and it is 95%.
- Rounding up. Report the figure as calculated, not a rounded-up one.
FAQ
How do I convert CGPA to percentage in CBSE?
Multiply the CGPA by 9.5. A CGPA of 8.6 is 8.6 × 9.5 = 81.7%. CBSE gives this as an indicative overall percentage for its 10-point grade scale.
Why is the CBSE multiplier 9.5 and not 10?
It is the factor CBSE publishes. A grade point stands for a band of marks (grade point 10 covers marks of 91 to 100), not an exact score, so the conversion gives 95% for a perfect CGPA rather than 100%. Multiplying by 10 would overstate your result.
Does CBSE give an official percentage?
No. CBSE states that it does not award an overall division or aggregate percentage, and that 9.5 × CGPA is only an indicative figure. If a college or an employer needs a percentage, ask which method it accepts.
What multiplier does my university use?
It varies, and some universities use a formula that is not a plain multiplier at all. 10 is common, but many are different, so look in your university's regulations or on your transcript. Enter the number as the custom multiplier. If it uses a formula that subtracts a constant first, work it out with that formula instead.
How do I convert a percentage back to CGPA?
Divide the percentage by the multiplier. For CBSE, 81.7 ÷ 9.5 = 8.6. The highest percentage CBSE's rule can turn into a CGPA is 95%, which is a CGPA of 10, so a higher percentage cannot be converted.
