How to Convert Percentage to CGPA
Different educational institutions use different scales for grades. Most Indian universities use a 10-point scale (CGPA), while US institutions typically use a 4-point scale (GPA).
Common Conversions
- Percentage to CGPA (Scale of 10): CGPA = Percentage / 10
- Percentage to GPA (Scale of 4): GPA = (Percentage / 100) × 4
Example: 75% on a 10-point scale = 7.5 CGPA. On a 4-point scale = 3.0 GPA.
Semester CGPA Calculation
To calculate your cumulative CGPA across multiple semesters, multiply each semester\'s CGPA by its credit hours, sum them all, then divide by total credits.
Cumulative CGPA = Σ(Semester CGPA × Credits) / Total Credits
Example: Multiple Semesters
- Sem 1: 7.8 CGPA × 20 credits = 156
- Sem 2: 8.1 CGPA × 20 credits = 162
- Sem 3: 7.5 CGPA × 20 credits = 150
- Total: 468 ÷ 60 credits = 7.8 cumulative CGPA
