Why the formulas differ
A 10-point CGPA is not a percentage. Each university sets its own relationship between grade points and marks, so the same CGPA can mean different percentages: a CGPA of 8.0 is 72.5% at VTU, 75% at JNTUH and GTU, 76% at Delhi University, 71.2% at SPPU and 80% at Anna University.

We only list universities whose formula we could confirm in an official document; the two “Other” options in the calculator are common rules, not official formulas.
Frequently asked questions
How do I convert CGPA to percentage?
Use your university's own formula. Many use CGPA × 10 (Anna University, RGPV), some CGPA × 9.5 (Delhi University CBCS, CBSE), and some subtract an offset first: VTU and MAKAUT use (CGPA − 0.75) × 10, JNTUH and GTU use (CGPA − 0.5) × 10.
Is CGPA × 9.5 correct for every university?
No. The 9.5 multiplier comes from CBSE and is also used by Delhi University for CBCS, but a VTU CGPA of 8.0 is 72.5% (not 76%), and an Anna University CGPA of 8.0 is 80%. Always check your own university's rule.
How is CGPA calculated from SGPA?
CGPA is the credit-weighted average of your semester SGPAs: multiply each SGPA by that semester's credits, add them up and divide by the total credits.
Which percentage should I put on a job or admission form?
If your university issues a CGPA-to-percentage conversion certificate or prints a conversion on the marksheet, use that. Otherwise use the formula from your university's regulations, as on this page.
