Converting Tamil Nadu Open University (TNOU), Chennai percentage back to CGPA
Tamil Nadu Open University (TNOU), Chennai (Tamil Nadu) officially converts CGPA to percentage with % = CGPA × 10 (derived; PG Diploma programmes, CY 2021 onward). 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 Tamil Nadu Open University (TNOU), Chennai formula is % = CGPA × 10 (derived; PG Diploma programmes, CY 2021 onward). Starting from a percentage of 76%, the formula reverses to a CGPA of about 7.6 on the 10-point scale. You can check this by running 7.6 through the forward Tamil Nadu Open University (TNOU), Chennai CGPA to percentage calculator — it returns 76%, 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.
