NIT Trichy CGPA to Percentage Calculator
NIT Trichy's Academic Office publishes a standard certificate for CGPA-to-percentage conversion, signed by the Dean (Academic) on 22 June 2021. It sets two rules. For students who passed out in 2010, the average percentage of marks = CGPA × 9.25. For all other batches, the average percentage = CGPA × 10.
So a CGPA of 8.47 is 84.7% for almost everyone, and 78.35% for a 2010 graduate. Choose the right batch in the calculator before you quote the figure, since the 2010 rule gives a noticeably lower number for the same CGPA.
The calculator also shows the class band from the B.Tech Regulations 2017 — 8.5 and above First Class with Distinction (with first-appearance conditions), 6.5 and above First Class, below that Second Class — and the reverse tool gives the CGPA needed for a percentage cut-off.
Under the default rule, the First Class threshold of 6.5 CGPA is 65% and the distinction threshold of 8.5 is 85%.

The official NIT Trichy CGPA to percentage rule
Rules from the NIT Tiruchirappalli B.Tech Regulations 2017, National Institute of Technology Tiruchirappalli:
- Letter grades are relative: the Performance Analysis Committee fixes the mark ranges for each course; the passing minimum is the higher of 35% and half the class average (B.9, B.10).
- GPA for a session = Σ(Ci × GPi) / ΣCi, computed only for students who passed all registered courses of that session; CGPA = Σ(Ci × GPi) / ΣCi over all N courses of the programme (B.16).
- E (after reassessment) and R (after formative assessment) both carry 5, the minimum grade point for completing a course. FF carries 2 and stays on the grade card and in the CGPA.
- A B.Tech (Honours) needs a CGPA of 8.5 and the conditions in B.4.5.3.
Average percentage = CGPA × 10 (NIT Trichy certificate, 22.06.2021)
Average percentage = CGPA × 9.25 for the 2010 pass-outs (NIT Trichy certificate, 22.06.2021)
