Source & verification
Anna University, Office of the Additional Controller of Examinations (University Departments), Letter No.001/ACOE(UDs)/2021 dated 15.07.2021 (ref Lr.No.3452/AU/CAC/CGPA2020 dated 29.12.2020), titled 'CGPA to Percentage Conversion', stated verbatim: 'The CGPA to Percentage conversion for all UG and PG programmes of Regulations R-2015, R-2018 and R-2019 are as follows: Percentage of Marks = CGPA X 10'. Corroborated for R-2021 by the Regulations 2021 (CBCS) grade-sheet conversion clause.
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. 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 — 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).
