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.
