Full form of CGPA its calculation and conversion
Cumulative Grade Point Average (CGPA)is a numerical measure of performance in multiple subjects and semesters in certain academic time period. CGPA is assigned to students at end of academic year for performance evaluation.Unlike the SGPA or GPA that measures the performance in a specific semester or subject CGPA gives an overall view of your standings in certain field.
How CGPA is calculated
There is certain formula to calculate CGPA:
CGPA = CGPA = ∑ (Gi x Ci)/∑ Ci
Factors upon which CGPA depends:
Grade points(Gi): Grade point is the value assigned to a specific course that is based on marks usually on a scale of 10 or 4 depending upon the educational grading system. For example on 10 grade scale marks are assigned the grades like this:
90 -100 marks = 10 grade points
80 – 89 marks = 9 grade points
70 – 79 marks = 8 grade points
60 – 69 marks = 7 grade points and so on
Credit points(Ci):
Credit points are numbers allocated according to the priority of the course e.g. if physics is your main subject then,
14 credit hours for physics,
Total weighted grade points:
Multiply grade points with credit hours to get total grade points in a specific academic course.
Steps to Calculate CGPA from Individual Grades
- list down all subjects that you have chosen for your career.
- You should know about the grades that are assigned to you in your transcript against these courses.
- now convert your grades to grade points according to the grading scale.
- you also have the credit hours or points against each subject or course.
- now multiply each grade point with each credit point to get weighted grade points in specific courses
- add up all course results and divide it by total credit points to get CGPA.
Example Calculation for Better Understanding
| SUBECTS | GRADE | GRADE POINTS | CREDITS |
|---|---|---|---|
| ENGLISH | B | 8 | 2 |
| MATH | C | 6 | 3 |
| CHEMISTRY | A | 10 | 5 |
| PHYSICS | B | 8 | 3 |
| ART | A | 10 | 2 |
ENGLISH (8*2)=16
MATH (6*3)=18
CHEMISTRY (10*5)=50
physics (8*3)=24
ART (10*2)=20
total grade points=16+18+50+24+20=
total credit points=2+3+5+3+2=
CGPA=total grade points/total credit points=
CGPA Grading Scales
educational institutions use different grading scales to assign grades to students. According to the grading scale grades for example A, B, C, and so on are assigned. Each grade is assigned a numerical value according to the grading scale which is the grade point that is used for CGPA competition.
Most common grading scales are grade 10, Grade 5 and Grdae 4.
4 Grading scale:
this ranges from 0 to 4 and is commonly used in United state institutions.
| GRADES | GRADE POINTS |
|---|---|
| A | 4 |
| B | 3 |
| C | 2 |
| D | 1 |
| F | 0 |
5 Grading scale:
This ranges from 0 to 5 and is commonly used in Europe and Asia universities.
| GRADES | GRADE POINTS |
|---|---|
| A | 5 |
| B | 4 |
| C | 3 |
| D | 2 |
| E | 1 |
| F | 0 |
10 Grading scale:
This scale is commonly used in India and many other universities.
| GRADES | GRADE POINTS |
|---|---|
| A | 10 |
| B | 8 |
| C | 6 |
| D | 4 |
| E | 2 |
| F | 0 |
Conversion of CGPA to Percentage and Vice Versa
CGPA is converted to percentage very easily. There is general factor that is 9.5 that is used for conversion. CGPA is multiplied by 9.5 for percentage conversion.
PERCENTAGE=CGPA*9.5
However, this conversion factor may change according to the policies of universities.
Percentage to CGPA:
with the same reverse formula, you can get cgpa from percentage.
CGPA=percentage/9.5
