Why might my university CGPA formula differ?

While most institutions follow standard weighted credit point formulas ($\text{SGPA} = \frac{\sum (C \times G)}{\sum C}$), some universities use custom percentage-to-GPA conversion factors (e.g. $\text{Percentage} = (\text{CGPA} - 0.75) \times 10$ or $\text{CGPA} \times 9.5$). Check your university's official handbook.
