Converting 7.5, 8.0 or 9.0 CGPA to percentage

“What is 8.0 CGPA in percentage?” is one of the most searched grading questions, usually with a specific value — 7.5, 8.0, 9.0. The honest answer is: it depends on your university's formula, but here is how to reason about it.

Under the common formulas

If your university uses a plain ×10: 7.5 CGPA → 75%, 8.0 → 80%, 9.0 → 90%. If it uses ×9.5 (CBSE-style): 7.5 → 71.25%, 8.0 → 76%, 9.0 → 85.5%. If it subtracts an offset first, for example (CGPA − 0.75) × 10: 8.0 → 72.5%. Same CGPA, materially different percentages.

Why the spread is so wide

A difference of half a point in the multiplier, or a small offset, compounds across the scale. That is why you cannot quote a single percentage for “8.0 CGPA” without knowing the institution — and why aggregator sites that give one fixed number are often wrong for your case.

Get your exact figure

Rather than memorise tables, enter your CGPA on your university's page in the CGPA to percentage calculator. It applies the official formula and shows it, so you can see why you got that percentage. You can also download a PDF of the result with the formula and source for your records or to attach to an application.

For the reverse — you have a percentage and need the CGPA — use the percentage to CGPA page, which inverts the same official formula.

Key takeaways

• The same CGPA gives materially different percentages under different formulas.
• Aggregator sites quoting one fixed number are often wrong for your university.
• Enter your value on your university's page for the exact, source-cited result.
• The converter can export a PDF with the formula and source.
