Converting Tata Institute of Social Sciences (TISS) percentage back to CGPA
Tata Institute of Social Sciences (TISS) (Maharashtra) officially converts CGPA to percentage with % = CGPA × 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 Tata Institute of Social Sciences (TISS) formula is % = CGPA × 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 on the 10-point scale. You can check this by running 8 through the forward Tata Institute of Social Sciences (TISS) 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.

Source & verification
The Tata Institute of Social Sciences (a deemed-to-be university) states the conversion in its 2025 Academic Rules & Guidelines, §4.4.4, as Percentage = Grade Point × 10, applied to the CGPA (CGPA 8.0 → 80%). TISS uses a ten-point letter-grade scale (O = 10 for ≥95%, A+ = 9 for 90–95%, A = 8 for 80–90%, B+ = 7 for 70–80%, B = 6 for 60–70%, C = 5 for 50–60%, P = 4 for 40–50%, F = 0 below 40%; minimum pass grade point 4.0, or 5.0 for LL.M.). For grades P through A the ×10 conversion lands exactly on the marks-band floor; the top two grades (A+ and O) are slightly compressed on the grade-point scale, so for very high scorers ×10 is the institute's stated equivalence rather than the exact marks obtained.
