Anna University Percentage Conversion: Affiliated R2021 Guide
Affiliated-college regulations and university-department regulations are separate documents.
Which record does this guide cover?
For the supported affiliated B.E./B.Tech R2021 record, use clause 15.5.3. Do not select the rule solely because your college appears in an Anna University search result: check whether it is autonomous and whether R2021 is the scheme shown on your grade sheet.
The verified preset is for affiliated institutions under Regulations 2021, clause 15.5.3. University departments, autonomous institutions and other regulations should be checked against their own documents.
Worked example using the supported expression
For 8.20 CGPA, the selected rule gives 82.00%. Keep the original grade-point value and the rule label together so that the saved result can be checked against its source.
| CGPA | Equivalent percentage |
|---|---|
| 6.00 | 60.00% |
| 7.00 | 70.00% |
| 8.00 | 80.00% |
| 9.00 | 90.00% |
Percentage = CGPA × 10

Questions about this Anna University calculation
Can university-department students use this preset automatically?
No. The verified preset concerns affiliated B.E./B.Tech Regulations 2021. Departmental or autonomous regulations need their own source.
Can one semester’s GPA stand in for the final result?
Use the period and metric requested by the application. A semester average and a cumulative record can describe different courses; calculate a credit-weighted average only under the relevant academic rules.
