What is a CGPA to percentage converter?
A CGPA to percentage converter turns a grade point average on a 10-point scale into the percentage that job portals, government forms and foreign universities often ask for, and turns a percentage back into CGPA when you need the reverse.
Because boards and universities use different formulas, this converter shows the CBSE ×9.5 method, the (CGPA − 0.75) × 10 method used by VTU and several engineering universities, the plain ×10 method, and a custom multiplier, all at once. You can compare them, pick yours, and copy the result with the formula named, which is what most application forms want.
How to use the CGPA to Percentage Converter
1.Choose the direction
CGPA to percentage, or percentage to CGPA.
2.Enter your score
Each formula card shows its own answer instantly.
3.Pick your formula
Tap the one your board or university uses, or enter its multiplier under Custom.
Example: a CGPA of 8.4
The same CGPA under each formula:
- CGPA × 9.5
- 79.8%
- (CGPA − 0.75) × 10
- 76.5%
- CGPA × 10
- 84%
- 80% back to CGPA (÷ 9.5)
- 8.42
The formulas differ by up to 7.5 percentage points for the same CGPA, which is why the one your university prints is the one to use.
Which formula should I use?
There's no single national formula for degree CGPAs. CBSE uses CGPA × 9.5 for Class 10 and 12, and many universities use the same factor when they don't specify one. VTU and several other engineering universities use (CGPA − 0.75) × 10, and some convert one-to-one with × 10.
Look at the back of your grade card or your university's ordinance first. If a form asks for a percentage and your university has no formula, write the CGPA and the formula you used, so the reader can check it.
Frequently asked questions
How do I convert CBSE CGPA to percentage?
Multiply by 9.5. A CGPA of 9 is 85.5%.
Why 9.5?
CBSE found that students in its top band (91–100 marks) averaged about 95 marks over earlier years. A grade point of 10 was matched to that 95, so each point is worth 9.5.
Can the (CGPA − 0.75) × 10 formula give silly results?
At very low CGPAs, yes; a 0.5 CGPA would give a negative percentage. The tool shows those at the limit.
Does this work for SGPA too?
Yes, the same formulas apply to a single semester's SGPA.
