Applications and job forms often ask for a percentage even when your marksheet shows a CGPA. This tool converts a 10-point CGPA into a percentage using the widely quoted CBSE factor, and lets you swap in your own factor if your university uses a different one.
The formula
The conversion multiplies your CGPA by a fixed factor:
Percentage = CGPA × factor (CBSE uses 9.5)
For example, for a CGPA of 8.2 with the CBSE factor of 9.5:
- Calculation = 8.2 × 9.5 = 77.9%
When this helps
- Applications — fill in a percentage field when only a CGPA is asked in the certificate.
- Eligibility checks — compare your score against a percentage cut-off.
- Resumes — quote a percentage alongside your CGPA for readers who expect it.
The 9.5 rule is a convention
Multiplying by 9.5 is the CBSE convention, not a universal law. Different boards and universities publish their own factors or exact conversion tables, and some do not permit a simple multiplier at all. Always use your own institution's official rule where one exists, and treat this as an approximation otherwise. To reverse the calculation, use the percentage to CGPA calculator; to work a percentage out directly from marks, the marks percentage calculator does that.
