Worked example
The official Chalapathi Institute of Engineering & Technology (CIET), Guntur formula is % = (CGPA − 0.5) × 10. Starting from a percentage of 70%, the formula reverses to a CGPA of about 7.5 on the 10-point scale.

Why this is an estimate, not an official figure
A college 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 can shift the back-calculated CGPA slightly. When both numbers appear on your grade card, always quote the official CGPA rather than this estimate.
