percentage to CGPA

National Institute of Technology, Tiruchirappalli (NIT Trichy) — % → CGPA

Forward formula: % = CGPA × 10Source: NIT Trichy certificate, Dean (Academic) Dr. Ramakalyan Ayyagari, dated 22.06.2021 — CGPA to Percentage ConversionStatus: verifiedLast verified: 2026-06-23 · NIT Trichy's official certificate gives two batch-specific formulas: the 2010 passing-out batch uses CGPA × 9.25, and all other batches use CGPA × 10. Most students use ×10 (CGPA 8.5 → 85%). (Note: some third-party calculators wrongly cite (CGPA−0.5)×10 or ×9.5 — the institute's certificate uses ×10.)
This reverses the official CGPA→% formula. A percentage on a transcript is the authoritative figure; the back-calculated CGPA is an estimate. Always confirm with your university.

Converting National Institute of Technology, Tiruchirappalli (NIT Trichy) percentage back to CGPA

Worked example

The official National Institute of Technology, Tiruchirappalli (NIT Trichy) formula is % = CGPA × 10. To go the other way, you rearrange it to solve for CGPA. Starting from a percentage of 85%, the formula reverses to a CGPA of about 8.5 on the 10-point scale.

Why this is an estimate, not an official figure

A university issues your percentage from your actual CGPA, not the other way around — so reversing the formula recovers the CGPA that would produce that percentage. It matches in almost every case, but rounding on your transcript (for example a percentage printed to one decimal place) can shift the back-calculated CGPA slightly. When both numbers appear on your grade card, always quote the official CGPA rather than this estimate.
