Understanding CGPA and Percentage Conversions
Cumulative Grade Point Average (CGPA) is an educational grading system used by schools and universities worldwide to measure a student's overall academic performance. Calculating your CGPA accurately helps you track your academic progress, apply for higher studies, and meet eligibility criteria for employment.
How to Calculate CGPA
CGPA is calculated by dividing the sum of the total grade points earned across all subjects by the total sum of credit hours attempted. Here is the step-by-step mathematical breakdown:
- Multiply the credit hours of each subject by the grade point obtained in that subject to get the credit points for each course.
- Sum up all the credit points earned across every subject.
- Sum up the total credit hours for all subjects.
- Divide total earned credit points by total credit hours.
CGPA to Percentage Conversion Formula
Most educational boards, including CBSE and major universities, utilize a standard multiplier to convert CGPA into an equivalent percentage.
Example: If your calculated CGPA is 8.4, your equivalent percentage is:
8.4 × 9.5 = 79.8%
Difference Between SGPA and CGPA
| Aspect | SGPA (Semester Grade Point Average) | CGPA (Cumulative Grade Point Average) |
|---|---|---|
| Scope | Measures performance in a single academic semester. | Measures cumulative performance across all completed semesters. |
| Duration | Short-term (usually 6 months). | Long-term (entire course or degree duration). |
| Calculation | Based solely on current semester courses. | Calculated by averaging all previous semester SGPAs or total cumulative credits. |
