⚠️ There is no universal conversion — CBSE uses ×9.5, many universities use ×10 or their own formula, and some publish lookup tables instead. For official purposes, always use the rule printed by your institution.
🔄One CGPA, three possible percentages — pick the right rule
An 8.2 CGPA is 77.9% under CBSE's ×9.5, 82% under a straight ×10, and 74.5% under VTU's formula — same student, three answers. That's why this converter leads with the rule: choose CBSE, ×10, VTU, or type your university's own linear formula, and get the exact percentage with your band and division, a full 5.0–10.0 conversion table with your score highlighted, and a downloadable conversion card for application forms.
📊Everything you'd want to know
- Three built-in rules — CBSE ×9.5, straight ×10, VTU (CGPA − 0.75) × 10 — plus a custom a×CGPA+b formula for any university.
- Band (Outstanding/Excellent/…) and university division (distinction/first/second) alongside the raw number.
- A full conversion table from 5.00 to 10.00 in 0.25 steps, with your CGPA highlighted.
- A PDF conversion card with the formula stated — handy when forms ask how you converted.
🧮The maths
CBSE derived 9.5 from the average marks of A1 grade-band students in a reference year — it's a statistical mapping, not arithmetic truth, which is why other universities legitimately use different factors. All common rules are linear, so the conversion is exact in both directions.
💡Which rule should you use?
- For CBSE school results: ×9.5, always.
- For university results: whatever your university's ordinance says — it's usually printed on the grade card or degree rules.
- For job applications: use your institution's official rule and name it; HR teams check.
- If your university publishes a lookup table instead of a formula, the table wins — use the custom fields to approximate only for personal reference.
💡 Frequently Asked Questions
How do I convert CGPA to percentage?+
Multiply by your institution's factor. CBSE uses percentage = CGPA × 9.5, many universities use ×10, and VTU uses (CGPA − 0.75) × 10. An 8.2 CGPA is 77.9% under CBSE — this converter applies whichever rule you select and shows the full table.
Why does CBSE use 9.5 and not 10?+
CBSE analysed the average marks of students in the top grade band (A1) in a reference year and found it close to 95% — hence each CGPA point maps to 9.5 percentage points. It's a calibrated statistical mapping rather than a mathematical identity.
What is 8.2 CGPA in percentage?+
77.9% under CBSE's ×9.5 rule, 82% under a straight ×10, and 74.5% under VTU's formula. The right answer depends on which institution issued your CGPA — select its rule in the converter.
Is 9.5 CGPA conversion valid for engineering universities?+
Usually not — ×9.5 is CBSE's school rule. Engineering universities prescribe their own: many use ×10, VTU uses (CGPA − 0.75) × 10, and some publish lookup tables. Check your university's ordinance and use the custom formula fields if needed.
What CGPA equals 75% (distinction)?+
Under CBSE ×9.5: 75 ÷ 9.5 ≈ 7.89 CGPA. Under ×10: 7.5. Under VTU: 8.25. Use our Percentage to CGPA converter for the reverse direction with the same rules.
