Worked example
The official Sona College of Technology, Salem formula is % = CGPA × 10. To go the other way, you rearrange it to solve for CGPA. Starting from a percentage of 85.0%, the formula reverses to a CGPA of about 8.5 on the 10-point scale. You can check this by running 8.5 through the forward Sona College of Technology, Salem CGPA to percentage calculator — it returns 85.0%, confirming the two directions agree.
Why this is an estimate, not an official figure
An institution issues your percentage from your actual CGPA, not the other way around — so reversing the formula recovers the CGPA that would produce that percentage. It matches in almost every case, but rounding on your transcript (for example a percentage printed to one decimal place) can shift the back-calculated CGPA slightly. When both numbers appear on your grade card, always quote the official CGPA rather than this estimate.
