Why do formulas differ?
In India, education is a state subject, and universities have the freedom to set their own grading benchmarks. Some universities like Mumbai University have unique offsets, while VTU follows a derivative of the 10-point scale. Using the wrong formula on a job application can lead to disqualification for "misreporting marks".
1. VTU (Visvesvaraya Technological University)
For engineering students in Karnataka, the formula is strictly regulated:
Percentage = (CGPA - 0.75) × 10
Example: A 7.75 CGPA is exactly 70.0%.
2. Mumbai University (MU)
MU has several systems, but for the Choice Based Credit System (CBCS):
Percentage = 7.1 × CGPA + 11
(Note: For CGPA below 7, different tables apply)
3. CBSE & Standard 10-Point Scales
The standard multiplier used by CBSE and many central universities:
Percentage = CGPA × 9.5
4. Anna University & KTU (Kerala)
These typically use a direct linear multiplier:
Percentage = CGPA × 10
