Converting Siddharth Institute of Engineering & Technology (Autonomous), Puttur percentage back to CGPA
Siddharth Institute of Engineering & Technology (Autonomous), Puttur (Andhra Pradesh) officially converts CGPA to percentage with % = (CGPA − 0.5) × 10.

The official Siddharth Institute of Engineering & Technology (Autonomous), Puttur formula is % = (CGPA − 0.5) × 10.

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. When both numbers appear on your grade card, always quote the official CGPA rather than this estimate.
