CGPA to GPA Conversion Formulas
Converting 10-Point CGPA to 4-Point GPA
The most common conversion formula is:
GPA (4.0 scale) = (CGPA / 10) × 4
Or simplified:
GPA = CGPA × 0.4
Example:

- 4-Point GPA: 8.5 × 0.4 = 3.4
Converting 5-Point CGPA to 4-Point GPA
GPA (4.0 scale) = (CGPA / 5) × 4
Or:
GPA = CGPA × 0.8
Example:
- 5-Point CGPA: 4.2
- 4-Point GPA: 4.2 × 0.8 = 3.36
