Converting Indian Institute of Science (IISc Bangalore) percentage back to CGPA
Indian Institute of Science (IISc Bangalore) (Karnataka) officially converts CGPA to percentage with % = CGPA × 10 (joined Aug 2016+, 10-point scale). 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 Indian Institute of Science (IISc Bangalore) formula is % = CGPA × 10 (joined Aug 2016+, 10-point scale). 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 Science (IISc Bangalore) CGPA to percentage calculator — it returns 85%, 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.

Two cohorts: students who joined from Aug 2016 use the 10-point scale (% = CGPA × 10). Students who joined before Aug 2016 use the older 8-point scale (% = CGPA × 12.5). IISc calls this a 'notional' conversion — grade points are not officially convertible to percentage.
