percentage to CGPA

Indian Institute of Science (IISc Bangalore) — % → CGPA

Forward formula: % = CGPA × 10 (joined Aug 2016+, 10-point scale)Source: IISc Notification Ref. IISc/Acad/CGPA-Conversion/2021, 14 Oct 2021 (Senate-approved 11 Nov 2019)Status: verifiedLast verified: 2026-06-23 · 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.
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 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 — 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 Science (IISc Bangalore) formula is % = CGPA × 10 (joined Aug 2016+, 10-point scale). 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 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 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.
