Converting Indian Institute of Space Science and Technology (IIST) percentage back to CGPA
Indian Institute of Space Science and Technology (IIST) (Kerala) officially converts CGPA to percentage with % = (CGPA − 0.50) × 10. 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 Space Science and Technology (IIST) formula is % = (CGPA − 0.50) × 10. To go the other way, you rearrange it to solve for CGPA. Starting from a percentage of 80%, 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 Space Science and Technology (IIST) CGPA to percentage calculator — it returns 80%, 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.
