Formula explicitly STATED in Anna University's own ACOE document (top-tier source: official conversion letter, read in full): 'Percentage of Marks = CGPA X 10' (CGPA 8.0 → 80%). The letter's stated scope is Regulations R-2015, R-2018 and R-2019 (all UG and PG programmes); R-2021 batches use the same flat ×10, per the R-2021 grade-sheet conversion clause and the CENTAC government table. Consistent with the award-of-class bands: First Class with Distinction at CGPA ≥ 8.50, First Class ≥ 6.50, Second Class below. Although Anna University's R-2021 uses relative (Box-Cox) grading for larger theory cohorts at the course level, the CGPA-to-percentage step itself is a flat ×10. The widely circulated (CGPA − 0.5) × 10 and (CGPA − 0.75) × 10 figures for 'Anna University' are content-farm contamination — (CGPA − 0.5) × 10 is actually the Pondicherry/CENTAC-default value — and must not be used. DISAMBIGUATION: Anna University = state technical university, Chennai — distinct from IIT Madras ((CGPA − 0.75) × 10 region), University of Madras (band classification, no stated conversion), and Annamalai University (separate DB key). Autonomous colleges affiliated to Anna University set their own conversion (see KCT, Kongu, KPRIET, Mepco, Bannari Amman entries, all plain ×10 under own regulations).
