About Us How to Convert SGPA to CGPA
Converting SGPA to CGPA is straightforward when you follow these steps:
Method 1: Simple Average (Equal Credits Per Semester)
Use this when all your semesters have the same total credits.
Step 1: List all your semester SGPAs
Step 2: Add them together
Step 3: Divide by the number of semesters
Method 2: Weighted Average (Different Credits Per Semester)
Use this when semesters have different total credits (common in most universities).
Step 1: List each semester's SGPA and its total credits
Step 2: Multiply each SGPA by its semester credits
Step 3: Add all the products from Step 2
Step 4: Add all the semester credits
Step 5: Divide the sum from Step 3 by the sum from Step 4
SGPA to CGPA Calculation Formula
Simple Average Formula (Equal Semester Credits)
Where n = number of semesters
Weighted Average Formula (Different Semester Credits)
Where:
- SGPAᵢ = SGPA of semester i
- Creditsᵢ = Total credits in semester i
Important: The weighted formula is more accurate and is used by most universities worldwide.
SGPA to CGPA Examples (With Calculation)
Example 1: Simple Average Method
Scenario: A student completed 4 semesters with equal credits (20 credits each).
| Semester | SGPA |
| Semester 1 | 7.5 |
| Semester 2 | 8.0 |
| Semester 3 | 8.2 |
| Semester 4 | 8.5 |
Calculation:
CGPA = (7.5 + 8.0 + 8.2 + 8.5) ÷ 4
CGPA = 32.2 ÷ 4
CGPA = 8.05
Result: The student's CGPA is 8.05
Example 2: Weighted Average Method
Scenario: A student completed 4 semesters with varying credits.
| Semester | SGPA | Credits | SGPA × Credits |
| Semester 1 | 7.5 | 18 | 135.0 |
| Semester 2 | 8.0 | 22 | 176.0 |
| Semester 3 | 8.2 | 24 | 196.8 |
| Semester 4 | 8.5 | 20 | 170.0 |
| Total | — | 84 | 677.8 |
Calculation:
CGPA = 677.8 ÷ 84
CGPA = 8.07
Result: The student's CGPA is 8.07
Notice: The weighted CGPA (8.07) differs slightly from the simple average (8.05) because Semester 3 had more credits, giving the higher SGPA (8.2) more weight.
Example 3: Real-World Engineering Student
Scenario: A B.Tech student after 6 semesters.
| Semester | SGPA | Credits | SGPA × Credits |
| Sem 1 | 7.2 | 20 | 144.0 |
| Sem 2 | 7.8 | 22 | 171.6 |
| Sem 3 | 8.1 | 24 | 194.4 |
| Sem 4 | 8.4 | 24 | 201.6 |
| Sem 5 | 8.6 | 22 | 189.2 |
| Sem 6 | 8.9 | 20 | 178.0 |
| Total | — | 132 | 1078.8 |
Calculation:
CGPA = 1078.8 ÷ 132
CGPA = 8.17
Result: The student's CGPA is 8.17

What Is SGPA?
SGPA (Semester Grade Point Average) is the average of grade points you earn in a single semester, weighted by the credits of each course.
Think of SGPA as your academic snapshot for one semester. It tells you how well you performed in that specific term, considering both your grades and the importance (credit weight) of each subject.
How SGPA Is Calculated
Your university calculates SGPA using this approach:
- Multiply each subject's grade point by its credit hours
- Add up all these values (credit points)
- Divide by the total credits for that semester
SGPA Formula:
Quick Example:
| Subject | Grade Point | Credits | Credit Points |
| Mathematics | 9 | 4 | 36 |
| Physics | 8 | 3 | 24 |
| Chemistry | 7 | 3 | 21 |
| Total | — | 10 | 81 |
SGPA = 81 ÷ 10 = 8.1
What Is CGPA?
CGPA (Cumulative Grade Point Average) represents your overall academic performance across all semesters of your degree program.
While SGPA measures one semester, CGPA is the big picture — it's the number that appears on your final transcript, degree certificate, and job applications.
Why CGPA Matters
- Transcripts: Universities report CGPA as your official academic score
- Job applications: Recruiters often set CGPA cutoffs (e.g., "minimum 7.0 CGPA")
- Higher studies: Graduate programs evaluate your CGPA for admissions
- Scholarships: Many awards require minimum CGPA thresholds
Difference Between SGPA and CGPA
| Aspect | SGPA | CGPA |
| Full Form | Semester Grade Point Average | Cumulative Grade Point Average |
| Scope | Single semester | Entire degree program |
| Changes | Fixed after semester ends | Updates each semester |
| Appears On | Semester marksheet | Final transcript & degree |
| Used For | Semester performance tracking | Job applications, admissions |
| Calculation Frequency | Once per semester | After every semester |
Key Insight
Your CGPA is essentially a "running average" of all your SGPAs. A strong SGPA in later semesters can improve a lower CGPA, but early performance still carries weight.

Benefits of Accurate SGPA to CGPA Conversion
1. Transcript Accuracy
When applying for higher studies abroad, universities require precise CGPA. A miscalculation could affect your eligibility.
2. Job Application Success
Many companies have CGPA cutoffs:
- Top consulting firms: 7.5+ CGPA
- Tech giants: 7.0+ CGPA
- Banking/finance: 6.5+ CGPA
Knowing your exact CGPA helps you apply confidently.
3. Percentage Conversion
Many applications require percentage instead of CGPA. The common formula is:
Percentage = (CGPA - 0.5) × 10 (varies by university)
An accurate CGPA ensures correct percentage conversion.
4. Academic Planning
Track how each semester affects your CGPA. This helps you:
- Set realistic targets
- Identify semesters to focus on
- Plan improvement strategies
5. Scholarship Eligibility
Merit scholarships often require minimum CGPA:
- Government scholarships: 6.0-7.0 CGPA
- University merit awards: 8.0+ CGPA
- International grants: 8.5+ CGPA
Common SGPA to CGPA Calculation Mistakes
Mistake 1: Ignoring Credit Differences
Wrong: Adding all SGPAs and dividing by semesters (when credits differ)
Right: Using weighted average with actual credit values
Impact: Can cause 0.1-0.3 CGPA error significant for cutoffs
Mistake 2: Rounding Too Early
Wrong: Rounding each SGPA before calculation
Right: Use full decimal values, round only the final CGPA
Example:
- Incorrect: (7.5 + 8.5) ÷ 2 = 8.0
- Correct: (7.48 + 8.52) ÷ 2 = 8.00
Mistake 3: Forgetting a Semester
Wrong: Excluding a poor-performing semester
Right: Include all semesters that universities calculate from complete records
Note: Some universities exclude the worst semester (check your policy)
Mistake 4: Using Wrong SGPA Scale
Wrong: Mixing 4.0 scale and 10.0 scale values
Right: Ensure all SGPAs are on the same scale
Mistake 5: Confusing Subject Credits with Semester Credits
Wrong: Using individual course credits in the weighted formula
Right: Use total semester credits (sum of all course credits in that semester)
