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.
