How it works
CBSE: % = CGPA × 9.5; proportional: % = CGPA ÷ scale × 100Frequently Asked Questions
How do I convert CGPA to percentage?
For CBSE and most Indian universities, multiply CGPA by 9.5: an 8.2 CGPA is 77.9%. Other institutions use the proportional method — CGPA ÷ scale × 100 — so always check which your university mandates.
Why 9.5 and not 10?
CBSE derived 9.5 from the average marks of students in each grade band, so it maps grades to realistic percentages rather than the theoretical maximum.
How do I convert a 4.0 GPA to percentage?
Proportionally, a 3.4/4.0 is 85% — but US institutions rarely convert GPA to percentage officially. For applications abroad, use the target institution's published conversion table if one exists.
