CGPA to percentage converter
Pick the formula your university uses, type your CGPA, and get the percentage instantly — or go the other way.
Which formula should I use?
There is no single national formula. Each university (and sometimes each scheme year or faculty) sets its own rule, so use the one printed on your marksheet or grade card, or in your university’s official circular. When a company or college asks for a percentage, give the one your university’s rule produces — and keep the circular handy.
The common rules are:
- CGPA × 10 — e.g. 8.2 → 82%
- CGPA × 9.5 — e.g. 8.2 → 77.9% (the CBSE-style rule)
- (CGPA − 0.5) × 10 — e.g. 8.2 → 77%
- (CGPA − 0.75) × 10 — e.g. 8.2 → 74.5%
If your university uses a different multiplier, choose “CGPA × another number”. If it uses a slab table instead of a formula, use the table on your grade card.
