CGPA to Percentage Calculator

Because CGPA grade points were built from mark bands whose top band (91–100 marks) maps to 10 points, the statistical average position within that band works out so that ×9.5 best reproduces the underlying percentage. CBSE derived 9.5 from actual board results data. Using ×10 would inflate every conversion — a 10.0 would claim an implausible flat 100%.

85.5%, from 9.0 × 9.5. That sits in the middle of the 80s, which surprises students who expect 90%, but it follows directly from the standard formula and matches the official CBSE conversion table. If a form gives you the choice, reporting your CGPA as-is alongside the converted figure avoids any misreading.

Your university's official formula governs anything that university verifies, such as degree transcripts and equivalence certificates. Several Indian universities use ×9.5, some use their own factor, and Anna University, for example, has used ×10. For third-party forms that specify no rule, ×9.5 is the widely accepted default; where a rule is specified, follow it exactly.

No. This converter runs 100% in your browser and stores nothing — the CGPA you enter is multiplied locally on your device and is never uploaded, logged, or shared. The conversion leaves no record behind when you close the page.

No. This tool is strictly for 10-point CGPAs using the ×9.5 standard. A GPA on the 4.0 scale converts through grade-band anchors instead — use the GPA to Percentage Converter for that. Applying ×9.5 to a 4.0-scale GPA would give a meaningless figure like 33.25% for a 3.5 GPA.

Not exactly — CBSE describes it as an indicative percentage. Your CGPA was rounded from subject grade points, so information about your exact marks was already compressed before conversion. The ×9.5 result is the accepted official estimate used on forms and applications, but your marksheet percentage, if you have one, is the precise figure.
