CGPA to Percentage Calculator

What is CGPA?

CGPA (Cumulative Grade Point Average) is a grading system used by many schools and universities in India to evaluate academic performance. Instead of percentage marks, students receive grade points on a scale (usually 0-10). CGPA represents the average of grade points obtained in all subjects, excluding the sixth additional subject in CBSE. Different institutions use different formulas to convert CGPA to percentage.

CGPA to Percentage Formulas

Different universities use different conversion formulas:

CBSE: Percentage = CGPA x 9.5

VTU: Percentage = (CGPA - 0.75) x 10

Anna University: Percentage = CGPA x 10

Mumbai University: Percentage = 7.1 x CGPA + 11

For example, a CGPA of 8.5 under CBSE equals 8.5 x 9.5 = 80.75%.
