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. 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. 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 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.

Tata Institute of Social Sciences — Academic Rules & Guidelines, Undergraduate & Postgraduate Programmes 2025, §4.4.4: 'The formula for conversion from Grade Point to Percentage: Grade point × 10'; read with the Table 4 letter-grade scale
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.
