Convert a CGPA to a percentage using the multiplier your board or university actually publishes. CBSE’s 9.5 is the best-known but it applies to CBSE’s own ten-point scale; several universities multiply by 10, and some publish their own factor.
There is no single national conversion. Applying the wrong multiplier overstates or understates a result on an application form, which is the mistake this page exists to prevent.
The conversion is one multiplication. The reason people get it wrong is that they learned one multiplier and apply it to every grade card they ever see, including ones issued on a different scale by an institution that publishes a different factor.
The 9.5 multiplier is CBSE’s own published conversion for its ten-point grading scale. It is not a general rule of arithmetic and it carries no authority over a university that has published something different.
Using it on a grade card from an institution that converts by multiplying by 10 understates the percentage by roughly five points, which on an eligibility cut-off is the difference between an application that is considered and one that is not.
Where a form asks for a percentage and your result is a CGPA, the safe answer is the conversion your own institution publishes, stated as such — "8.4 CGPA (78.8% by the university’s published conversion)". Where the form will not take that, use the institution’s factor and keep the grade card, because a discrepancy discovered later is treated as a misstatement rather than a rounding choice.
Phrased the way they arrive, answered so each one stands on its own.
Because CBSE publishes 9.5 as the conversion for its own ten-point scale. It is a published convention, not a mathematical identity, and it does not govern other institutions.
Whichever your university publishes — it is usually printed on the grade card or in the regulation. The calculator takes a custom multiplier for exactly this reason.
Divide by the same factor. Be careful quoting a back-converted CGPA on a form, because it is a derived figure rather than what your institution awarded.
