CGPA to percentage
Convert between CGPA and percentage using the formula your institution uses.
Put in your CGPA and we will convert it with the formula you picked.
How to convert CGPA to percentage
There is no single formula, and that is the thing worth knowing before anything else. The conversion is set by your board or university, not by any general rule.
Pick the one your institution states and the answer appears, with the formula printed beside it so you can check it against your own paperwork.
Why the answer moves so much
On a CGPA of 8, CBSE's formula gives 76%, the (CGPA − 0.75) × 10 rule gives 72.5%, and the straight × 10 gives 80%. That is a spread of seven and a half points from the same result.
On a job form or a university application that difference matters, which is why we show you the formula rather than quietly picking one.
Common questions
How do I convert CGPA to percentage?
Choose the formula your board or university uses, then put in your CGPA.
CBSE officially uses percentage = CGPA × 9.5. Many Indian universities use (CGPA − 0.75) × 10. Some use CGPA × 10.
Which CGPA formula should I use?
The one your own institution states. It is usually printed on the marksheet, in the results notice or on the university website.
If you cannot find it, ask the examination office rather than guessing. The formulas differ by several percentage points, which is enough to change how an application is read.
What is 8 CGPA in percentage?
It depends on the formula. 76% under CBSE, 72.5% under (CGPA − 0.75) × 10, and 80% under CGPA × 10.
There is no correct answer without knowing which rule applies to you.
How do I convert percentage back to CGPA?
Switch the direction at the top of the calculator and put your percentage in. It reverses whichever formula you have selected.
Does this work for a 4.0 GPA?
There is a rough 4.0 option, which multiplies by 25. Treat it with caution — many universities do not accept a straight conversion from a GPA to a percentage, and several use their own tables instead.
If it is for an application, use whatever conversion the receiving institution asks for.
