Many students in India think every university follows the same grading system. But that’s not true. Each one—like VIT, SRM, Anna University, or Amity—has its own way to calculate GPA, SGPA, and CGPA.
The problem starts when students apply for internships, jobs, or foreign universities. Forms often ask for “percentage,” but their CGPA may not match others’. This is where VistaCalculator helps. It adjusts for each university’s rule and gives the exact result in seconds.
Let’s see how grading systems differ and how you can make sense of it all.
What Is GPA, SGPA, and CGPA?
Before comparing, let’s get clear on what these mean.
GPA (Grade Point Average): Average grade point for a short course or one term.
SGPA (Semester Grade Point Average): Average for a semester, based on subject credits.
CGPA (Cumulative Grade Point Average): Total average across all semesters.
All three use grade points and credits, but the formula and weightage differ per university.
VIT University Grading System
Vellore Institute of Technology (VIT) follows a credit-based grading system.
Each subject carries credits (1 to 4), and grades are assigned on a 10-point scale.
| Grade | Grade Point | Description |
|---|---|---|
| O | 10 | Outstanding |
| A+ | 9 | Excellent |
| A | 8 | Very Good |
| B+ | 7 | Good |
| B | 6 | Average |
| C | 5 | Satisfactory |
| P | 4 | Pass |
| F | 0 | Fail |
Formula:
SGPA = (Sum of Grade Points × Credits) ÷ Total Credits
CGPA = (Sum of SGPAs) ÷ Total Semesters
Conversion Rule:
Percentage = (CGPA − 0.5) × 10
Example:
If your CGPA is 8.2,
Percentage = (8.2 − 0.5) × 10 = 77%
Scenario 1: VIT Student
Priya studies at VIT and just finished her fifth semester. She wants to know if her 8.2 CGPA equals the 75% required for her internship.
She opens Vista Calculator, selects VIT CGPA Converter, enters 8.2, and gets 77%. Now she can fill her form without confusion.
SRM University Grading System
SRM Institute of Science and Technology also uses a 10-point scale, but with slightly different grade mapping.
| Grade | Grade Point |
|---|---|
| O | 10 |
| A+ | 9 |
| A | 8 |
| B+ | 7 |
| B | 6 |
| C | 5 |
| P | 4 |
| F | 0 |
Conversion Formula:
Percentage = (CGPA × 10)
This means SRM students often have higher “percentage” values than VIT students with the same CGPA.
Example:
8.2 CGPA = 82% (in SRM), but only 77% (in VIT).
Scenario 2: SRM Student
Ravi from SRM applies for a government job that asks for 75%. His CGPA is 7.8. He uses Vista Calculator and finds it equals 78% for SRM’s rule.
He realizes he qualifies. Without the tool, he might have misjudged his eligibility.
Anna University Grading System
Anna University uses grades and credits, but the scale is slightly different:
| Grade | Grade Point | Description |
|---|---|---|
| S | 10 | Outstanding |
| A | 9 | Excellent |
| B | 8 | Very Good |
| C | 7 | Good |
| D | 6 | Average |
| E | 5 | Pass |
| U | 0 | Fail |
Conversion Formula:
Percentage = (CGPA × 10)
Anna University often rounds CGPA to two decimal places. So, a CGPA of 8.36 becomes 83.6%.
Scenario 3: Anna University Student
Meena is preparing for higher studies in the UK. The university there asks for “70% or First Class.” She has an 8.1 CGPA.
She checks Vista Calculator, selects Anna University, and converts 8.1 to 81%. She’s well above the cut-off and applies confidently.
Amity University Grading System
Amity follows a mixed grade rule. Its 10-point scale uses letters but includes more steps.
| Grade | Grade Point | Description |
|---|---|---|
| A+ | 10 | Exceptional |
| A | 9 | Excellent |
| B+ | 8 | Very Good |
| B | 7 | Good |
| C+ | 6 | Average |
| C | 5 | Satisfactory |
| D | 4 | Pass |
| F | 0 | Fail |
Conversion Formula:
Percentage = (CGPA × 9.5)
Example:
If your CGPA is 8.0,
Percentage = 8.0 × 9.5 = 76%.
Why These Differences Matter
If all universities use 10-point scales, why is the percentage different?
Because the conversion rule varies.
A 9.0 CGPA at SRM equals 90%, while the same CGPA at VIT equals 85%.
This gap creates confusion when students from different universities apply for the same job or higher studies.
How Vista Calculator Fixes This
Vista Calculator solves this confusion by using university-specific formulas.
When you open it, you can:
Select your University.
Enter your CGPA or SGPA.
Click Calculate.
You get an instant, correct conversion based on your campus rules.
Benefits:
No need to remember formulas.
100% accuracy.
Saves time.
Works for students, graduates, and employees.
Scenario 4: A Working Employee
Amit graduated from VIT and now works in a tech company. He wants to apply for a job in another country. The form asks for his percentage.
He doesn’t remember VIT’s conversion formula.
He goes to Vista Calculator, selects VIT CGPA to Percentage, enters his CGPA, and gets the right percentage instantly.
This helps him avoid any data errors during document verification.
Key Takeaways
Let’s summarize the main differences:
| University | Formula | Example (8.0 CGPA) |
|---|---|---|
| VIT | (CGPA − 0.5) × 10 | 75% |
| SRM | CGPA × 10 | 80% |
| Anna University | CGPA × 10 | 80% |
| Amity University | CGPA × 9.5 | 76% |
These small changes can affect your career applications, eligibility, or visa documents.
Why You Should Always Use a Calculator
