Indian Institute of Engineering Science and Technology (IIEST), Shibpur — % → CGPA

Forward formula: % = (CGPA − 0.5) × 10Source: IIEST Shibpur — Ordinances for Undergraduate Programmes (UG Ordinances 2025; also in the 2019 ordinances), Evaluation System: 'In case of a specific query by a student/employer/any other Institute regarding conversion of CGPA into percentage marks, the following formula may be adopted for notional conversion of CGPA into percentage marks: % Marks = (CGPA − 0.5) × 10.' Corroborated by IIEST's HRM/placement notice: 'The percentage marks should be calculated from such CGPA using the formula: % Marks = (CGPA − 0.5) × 10 as applicable for IIEST.'Status: verifiedLast verified: 2026-06-23 · Formula STATED in IIEST Shibpur's own UG Ordinances (2025 and 2019 versions read/confirmed): for notional conversion of CGPA into percentage, % Marks = (CGPA − 0.5) × 10. This is reaffirmed verbatim in IIEST's official placement (HRM department) notice as the formula 'as applicable for IIEST'. 10-point scale (S=10 for 90–100%, A=9, B=8, C=7, D=6, E=5 for 40–50%, F below). IMPORTANT: Many student forum answers (Quora/Collegedunia) wrongly claim 'IIEST has no CGPA-to-percentage rule' or suggest ×9.5/×10 — these are incorrect; IIEST's ordinance specifies (CGPA − 0.5) × 10 as the notional conversion. DISAMBIGUATION: IIEST Shibpur (Institute of National Importance in Howrah, formerly Bengal Engineering College / BESU) is distinct from IISc Bangalore (which uses plain CGPA × 10) and from Jadavpur University.
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 Indian Institute of Engineering Science and Technology (IIEST), Shibpur percentage back to CGPA

Indian Institute of Engineering Science and Technology (IIEST), Shibpur (West Bengal) officially converts CGPA to percentage with % = (CGPA − 0.5) × 10. This page inverts that formula so you can estimate the CGPA behind a known percentage — useful when a scholarship form, job portal or foreign application asks for CGPA but your marksheet only shows a percentage. Enter your percentage above and the calculator solves for the CGPA on the 10-point scale.

Worked example

The official Indian Institute of Engineering Science and Technology (IIEST), Shibpur formula is % = (CGPA − 0.5) × 10. To go the other way, you rearrange it to solve for CGPA. Starting from a percentage of 75%, the formula reverses to a CGPA of about 8 on the 10-point scale. You can check this by running 8 through the forward Indian Institute of Engineering Science and Technology (IIEST), Shibpur CGPA to percentage calculator — it returns 75%, confirming the two directions agree.

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.
