IIT Madras CGPA Percentage: Match the Graduation Date
The IIT Madras conversion boundary is a specific graduation date.
Which record does this guide cover?
The official sheet separates graduates from 11 November 2020 from those who graduated up to 10 November 2020. Do not select a rule by admission year or simply use the newest option. The same final CGPA gives different numerical results under the two expressions.
The official sheet separates graduation dates: from 11 November 2020 use ×10; up to 10 November 2020 use 55 + 10(CGPA −6), equivalent to 10×CGPA −5. Choose the graduation-date rule, not an admission-year guess.
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
Compare the supported options before choosing
Different presets represent different scopes. The comparison below is an arithmetic illustration; it does not let you choose a rule on the basis of the higher result.
| Rule or scope | Example input | Example result |
|---|---|---|
| students graduating from 11 November 2020 | 8.00 | 80.00% |
| Graduated up to 10 November 2020 | 8.00 | 75.00% |
