SGPA to CGPA Formula
CGPA is not a simple average when credit hours differ. It is a weighted average across semesters.
Formula:
CGPA = sum(SGPA x Semester Credits) / sum(Semester Credits)
Equal Credits Case
If all semesters have equal credits, CGPA is close to the arithmetic average of SGPAs.
Unequal Credits Case
Higher-credit semesters influence CGPA more than low-credit semesters.
