📌 Formula for Calculating CGPA from GPA
🏆 Step-by-Step Guide to Calculating CGPA from GPA
Step 1: Gather Your Semester GPA and Credit Units
To calculate CGPA, you need:
- Your GPA for each semester
- The total credit units for each semester
Step 2: Multiply Each GPA by Its Semester’s Credit Units
For each semester, multiply your GPA by the total credit units for that semester.
Step 3: Sum Up the Total Quality Points and Total Credit Units
- Add up all the quality points (GPA × Total Credit Units per semester).
- Add up all the credit units across all semesters.
Step 4: Calculate CGPA
Now, divide the total quality points by the total credit units to get your CGPA.
🎓 Example of CGPA Calculation from GPA
Let’s assume you have the following GPA and credit units for each semester:
| Semester | GPA | Total Credit Units (TCU) | Quality Points (GPA × TCU) |
|---|---|---|---|
| 1st | 3.5 | 18 | 3.5 × 18 = 63 |
| 2nd | 3.8 | 20 | 3.8 × 20 = 76 |
| 3rd | 3.6 | 22 | 3.6 × 22 = 79.2 |
| 4th | 3.2 | 19 | 3.2 × 19 = 60.8 |
Step 1: Calculate Total Quality Points
63+76+79.2+60.8=27963 + 76 + 79.2 + 60.8 = 279
Step 2: Calculate Total Credit Units
18+20+22+19=7918 + 20 + 22 + 19 = 79
Step 3: Calculate CGPA
CGPA=27979=3.53CGPA = \frac{279}{79} = 3.53
✅ Final CGPA = 3.53 (Second Class Upper)
