GPA Calculator: CGPA to Percentage & 4.0 Scale Conversion
CGPA × 9.5 = Percentage? Not Always
The popular "multiply by 9.5" formula only works for CBSE 10th grading (loosely). For university CGPA on a 10-point scale, and for conversions to the 4.0 GPA scale used abroad, you need different formulas. Using the wrong one on grad school applications can misrepresent your academic record.
Common Conversion Tables

How to Calculate CGPA
CGPA = Σ(Subject Grade Point × Credits) / Σ(Credits)
Each subject’s grade point is weighted by its credit hours. A 4-credit subject counts twice as much as a 2-credit subject. This is why performing well in high-credit courses matters more for your CGPA.
