IIT Kharagpur Percentage: Historical Cohorts Through 2024–25
This guide deliberately stops where the verified historical certificate stops supporting the presets.
Which record does this guide cover?
The March 2025 source separates graduates through 2020–21 from a later expression used here only for 2021–22 to 2024–25. A reported subsequent revision for 2025–26 onward has not been verified from a newer certificate. Do not use these historical presets to fill that evidence gap.
The inspected March 2025 certificate gives ×10 notionally for graduates through 2020–21 and a separate formula from 2021–22. This page supports historical cohorts through 2024–25 only. A reported later revision for 2025–26 onward has not been verified from a newer official certificate, so that cohort is not supported here.
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 | Notional percentage |
|---|---|
| 6.00 | 60.00% |
| 7.00 | 70.00% |
| 8.00 | 80.00% |
| 9.00 | 90.00% |
Notional 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 |
|---|---|---|
| graduated 2020–21 or earlier — notional conversion | 8.00 | 80.00% |
| Graduated 2021–22 to 2024–25 — March 2025 source | 8.00 | 77.14% |

Keep a usable report
Save the PDF with the original academic record when you need a portable calculation. Print report prepares the same calculation for paper; Download image produces a PNG. The source and scope are part of the report, so keep them visible when explaining the result.
Share opens a preview. It starts with the tool link; Include current result adds the entered values and calculation details. Review that preview before sharing. Website reports are independent calculations and do not replace certificates issued by the awarding institution.
Questions about this IIT Kharagpur calculation
Can a 2025–26 graduate use this guide’s later preset?
That cohort is not supported here. Obtain the newer applicable official conversion certificate before calculating it.
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.
