CGPA to Percentage Calculator
Convert CGPA to percentage (and back) using the CBSE ×9.5 rule, the simple ×10 rule, or the (CGPA − 0.75) × 10 university formula.
There is no single universal formula — CBSE's ×9.5 was derived from board-topper average marks, while many universities (Mumbai, VTU, AKTU and others) gazette their own conversion. For job applications and visa/WES evaluations, always use the formula printed on YOUR university's official conversion certificate; this tool covers the three formulas that dominate Indian academia.

About CGPA to Percentage Calculator
Every Indian student hits this conversion eventually: the marksheet says CGPA 8.2, but the job portal, scholarship form, or foreign-university application demands a percentage. This calculator converts CGPA to percentage — and percentage back to CGPA — using the three formulas that cover almost every Indian board and university: CBSE's famous × 9.5 rule, the simple × 10 rule many 10-point universities use, and the (CGPA − 0.75) × 10 formula used by Mumbai University, VTU and similar institutions. Pick the direction, pick your institution's formula, and get the converted figure plus the exact formula applied, ready to quote on the form.

Frequently asked questions
Why does CBSE multiply CGPA by 9.5 instead of 10?+
CBSE studied the marks of students scoring A1 (top grade) across five subjects and found their average was about 95%, not 100% — so one CGPA point ≈ 9.5 percentage points. A perfect 10 CGPA therefore maps to 95%, not 100%. It's an empirical equivalence, not exact arithmetic, which is why CBSE itself calls it an 'indicative' percentage.
Which formula should I use for my university?+
Use the formula your university officially gazettes — it's usually printed on the degree certificate, the conversion certificate, or the academic ordinances page. CBSE school results use × 9.5. Many NITs/IITs and 10-point universities accept × 10 or issue their own certificate. Mumbai University and VTU-pattern institutions use (CGPA − 0.75) × 10. When an employer just says 'convert your CGPA', attach the official certificate.
What is 8.2 CGPA in percentage?+
Depends on the formula: CBSE × 9.5 gives 77.9%, simple × 10 gives 82%, and (8.2 − 0.75) × 10 gives 74.5%. The spread is why you must use your own institution's formula — the same CGPA differs by up to 7–8 percentage points between conversion rules, which can matter for cutoffs.
Do foreign universities and WES accept these conversions?+
Credential evaluators like WES generally re-derive their own US-scale GPA from your individual marks rather than trusting a converted percentage. For applications, report what your transcript shows, attach your university's official conversion certificate if one exists, and let the evaluator convert. Never self-convert with an unofficial formula on a legal form.
