The important detail
Why the multiplier matters
CGPA conversion is not governed by one formula that applies everywhere.
Formula
Percentage = CGPA × multiplier
For example, a CGPA of 8.2 with a multiplier of 9.5 gives 77.9%. The example demonstrates the arithmetic, not a universal academic policy.
Verify before relying on it
There is no universal conversion multiplier
Institutions can publish different formulas, scales, or conversion tables. Confirm the official rule with your institution or transcript guidance, then enter that multiplier above. If your institution does not use a simple multiplication rule, this calculator may not represent its official conversion.
FAQ
Why is 9.5 shown by default?
It is a familiar example multiplier that makes the tool easy to try. It is not presented as the correct rule for every institution. Replace it with the multiplier your official guidance provides.
Can I use a custom multiplier?
Yes. The multiplier field is editable, so you can enter the value specified for your grading system.
What if my institution uses a conversion table?
A table or another formula may not be represented by CGPA × multiplier. Use your institution’s published conversion directly rather than treating this estimate as official.
