Converting Ispat Autonomous College, Rourkela percentage back to CGPA
Ispat Autonomous College, Rourkela (Odisha) officially converts CGPA to percentage with % = (CGPA − 0.50) × 10 for 4 < CGPA ≤ 10; % = CGPA × 10 for CGPA ≤ 4 — Odisha Model Regulation (+3 UG CBCS, 2019-20), cl. 9.5. This page inverts that formula so you can estimate the CGPA behind a known percentage. Enter your percentage above and the calculator solves for the CGPA on the 10-point scale.
Worked example
The official Ispat Autonomous College, Rourkela formula is % = (CGPA − 0.50) × 10 for 4 < CGPA ≤ 10; % = CGPA × 10 for CGPA ≤ 4 — Odisha Model Regulation (+3 UG CBCS, 2019-20), cl. 9.5. Starting from a percentage of 75%, the formula reverses to a CGPA of about 8 on the 10-point scale. You can check this by running 8 through the forward Ispat Autonomous College, Rourkela CGPA to percentage calculator — it returns 75%, confirming the two directions agree.
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.
