Converting International Institute of Management Sciences percentage back to CGPA
International Institute of Management Sciences (West Bengal) officially converts CGPA to percentage with % = (CGPA − 0.75) × 10. This page inverts that formula so you can estimate the CGPA behind a known percentage. Enter your percentage above and the calculator solves for the CGPA on the 10-point scale.
Worked example
The official International Institute of Management Sciences formula is % = (CGPA − 0.75) × 10. Starting from a percentage of 60.5%, the formula reverses to a CGPA of about 6.8 on the 10-point scale. You can check this by running 6.8 through the forward International Institute of Management Sciences CGPA to percentage calculator — it returns 60.5%, confirming the two directions agree.
Why this is an estimate, not an official figure
A college issues your percentage from your actual CGPA, not the other way around — so reversing the formula recovers the CGPA that would produce that percentage. When both numbers appear on your grade card, always quote the official CGPA rather than this estimate.
Source & verification
MAKAUT (Maulana Abul Kalam Azad University of Technology, West Bengal) official circular 'How to Calculate Percentage from Your Grade Point' — publishes the DGPA-to-percentage conversion table directly: GPA 6.25→55%, 6.75→60%, 7.25→65%, 7.75→70%, 8.25→75%, confirming % = (GPA − 0.75) × 10 across every row. University-wide formula; admission runs via JEMAT, MAKAUT's own MBA entrance exam.
Searched iimskolkata.org directly — no dedicated CGPA-formula document found. No autonomy claim found anywhere for THIS institution specifically. DATA QUALITY FLAG: one third-party listing attached text describing 'Category-1 Deemed to be University by UGC' status and international rankings to this listing — this appears to be data-mixing with an entirely different, unrelated institution (there are other 'Institute of Management Sciences' entities globally, including a deemed university elsewhere). Every other source consistently and correctly describes IIMS Kolkata as private, self-financed, MAKAUT-affiliated, established 1979, admitting via JEMAT/MAT. Treated as a standard non-autonomous MAKAUT affiliate here. Side note found during this search: MAKAUT's (CGPA−0.75)×10 formula is the subject of an active Change.org petition from MAKAUT students requesting a switch to the flat ×10 used by IITs/NITs — confirms the offset is a well-known, if unpopular, official rule rather than an obscure or disputed one.
