SGPA Calculator
SGPA Calculator: free, instant and private. Credit-weighting is where self-calculations go wrong: an A in a 4-credit course pulls twice as hard as an A in a 2-credit lab.
How the SGPA Calculator works
The SGPA Calculator takes Grade points and credits per line (e.g. "9 4"), Scale and returns the answer instantly — no button to hunt for, no page reload. Credit-weighting is where self-calculations go wrong: an A in a 4-credit course pulls twice as hard as an A in a 2-credit lab. The (GPA − 0.75) × 10 conversion is the widely used CBSE-style mapping — some universities publish their own table, so check before quoting a percentage on a form.
Enter your own numbers to replace the example values; the result panel updates as you type. Everything runs in this single page, so nothing you enter leaves your device.
Formula used
