percentage to CGPA

Indian Institute of Technology Bombay (IIT Bombay) — % → CGPA

Forward formula: % = CGPA × 10 (notional)Source: IIT Bombay — CPI to Percentage Conversion certificate (Academic Office); also stated on the reverse of the transcriptStatus: verifiedLast verified: 2026-06-23 · IIT Bombay frames the CPI as not formally convertible into a percentage, but notionally the CPI may be multiplied by 10 (CPI 8.5 → 85%); students passing out from 2016 onward convert by ×10 per the rule printed on the transcript. IIT Bombay uses the terms SPI/CPI for SGPA/CGPA and a two-letter grade scale (AA, AB, BB, …).
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 Technology Bombay (IIT Bombay) percentage back to CGPA

Indian Institute of Technology Bombay (IIT Bombay) (Maharashtra) officially converts CGPA to percentage with % = CGPA × 10 (notional). 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 Technology Bombay (IIT Bombay) formula is % = CGPA × 10 (notional). 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. You can check this by running 8.5 through the forward Indian Institute of Technology Bombay (IIT Bombay) CGPA to percentage calculator — it returns 85%, 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.
