What is GPA, CGPA and SGPA?
- GPA- GPA or the Grade Point Average is used to measure a student’s overall academic performance in a specific semester, an academic year, or the entire course. It is calculated by averaging the grade points earned in all courses during that period.
- CGPA– CGPA or the Cumulative Grade Point Average is the average of the overall grades earned by a student across all semesters or academic years completed.
- SGPA- SGPA or the Semester Grade Point Average is the average of the grade points earned by a student in a particular semester or term giving a more specific snapshot of the performance.
Differences between GPA, CGPA and SGPA
If the above descriptions couldn’t make much sense to you, here is a detailed description of GPA, CGPA and SGPAs:
| Basis of Classification | GPA | CGPA | SGPA |
|---|---|---|---|
| Calculation | Divide the total number of grade points earned by the total number of credit hours attempted. | Add the grade points earned in all courses taken across all semesters or academic years and divide the total by the total number of credit hours attempted. | Add the grade points earned in all courses taken during a particular semester and divide the total by the total number of credit hours attempted in that semester. |
| Scale | GPA is calculated on a scale of 0.0 to 4.0 | CGPA is calculated on a scale of 4, 7, 8 or 10 depending on the country | SGPA is calculated on a scale of 0.0 to 10 |
| Time Period | GPA is calculated for a specific period, usually a semester or an academic year. | CGPA is calculated over the entire duration of a program or course. | SGPA is calculated for a specific semester. |
| Significance | GPA is used to determine a student’s academic standing for a particular period, and it is often used by universities and employers to evaluate a student’s performance. | CGPA is used to determine a student’s overall academic performance across all semesters or academic years. | SGPA is used to determine a student’s performance in a particular semester |

Conversions of GPA, CGPA, SGPA, and Percentage
Now that you are aware of all the grade metrics, let us learn how to convert the different grade points.
How To Convert GPA To CGPA?
To calculate CGPA from GPA, you need to consider the credit hours or weightage of each course. The CGPA represents the average of GPAs earned over multiple semesters or academic terms.
- Calculate GPA for each semester: Calculate the GPA for each individual semester using the steps outlined in the previous section. This involves assigning numerical values to letter grades and calculating an average based on the credit hours or weightage of each course for that particular semester.
- Determine the credit hours: Determine the total credit hours or weightage earned in each semester. This information is typically available on your academic transcript or can be obtained from your institution’s registrar’s office.
- Calculate total grade points: Multiply the GPA of each semester by the credit hours or weightage earned in that semester. This will give you the total grade points earned for each semester.
- Calculate CGPA: Divide the total grade points earned across all semesters by the total credit hours. The resulting value will be your CGPA.
| CGPA = (Total Grade Points earned across all semesters) / (Total Credit Hours) |
How To Convert GPA To SGPA?
To calculate SGPA from GPA, you need to consider the credit hours or weightage of each course in the specific semester. SGPA represents the average GPA achieved in a single semester.
- Calculate GPA for each course: Calculate the GPA for each individual course in the semester as mentioned above.
- Determine the credit hours: Determine the credit hours or weightage assigned to each course in the semester. This information is typically available on your course schedule or can be obtained from your institution’s registrar’s office.
- Calculate weighted grade points: Multiply the GPA of each course by the credit hours or weightage assigned to that course. This will give you the weighted grade points earned for each course.
- Calculate total credit hours: Add up the credit hours or weightage assigned to all the courses in the semester. This will give you the total credit hours for the semester.
- Calculate total weighted grade points: Add up the weighted grade points earned for all the courses in the semester. This will give you the total weighted grade points.
- Calculate SGPA: Divide the total weighted grade points by the total credit hours. The resulting value will be your SGPA.
| SGPA = (Total Weighted Grade Points) / (Total Credit Hours) |
How To Convert GPA To Percentage?
- Determine the grading scale: Find out the grading scale used by your institution.
- Assign percentage values to each letter grade: Once you have the grading scale, assign the corresponding percentage values to each letter grade.
- Calculate GPA percentage: Multiply the GPA by the maximum percentage value to get the equivalent percentage.
- Round off the percentage: Depending on your institution’s rounding policy, round off the calculated percentage to the nearest whole number or to a specified decimal place.
| GPA Percentage = (GPA / Maximum GPA) * 100 |
How To Convert CGPA To Percentage?
Here are the steps to calculate the percentage from CGPA:
- Subtract 0.5 from the CGPA you want to convert. This adjustment is made because the percentage scale typically starts from 0 rather than 0.5.
- Multiply the result by 10. This is done to scale up the adjusted CGPA to the percentage scale, as 1 CGPA is usually equivalent to 10%.
| Percentage = (CGPA – 0.5) * 10 |
How To Convert SGPA To CGPA?
To calculate CGPA from SGPA, you need to consider the credit hours associated with each semester. The CGPA is the weighted average of all the SGPA values. Here are the steps to calculate CGPA from SGPA:
- Determine the total credit hours completed so far. This includes all the credit hours from the previous semesters as well as the current semester.
- Calculate the total grade points earned. Multiply the SGPA of each semester by the credit hours of that semester and sum up these values for all the semesters.
| Total Grade Points = (SGPA1 * Credits1) + (SGPA2 * Credits2) + … + (SGPAn * Creditsn) |
- Calculate the total credit hours earned. Add up all the credit hours from all the semesters.
| Total Credit Hours = Credits1 + Credits2 + … + Creditsn |
- Divide the total grade points earned by the total credit hours earned to obtain the CGPA.
| CGPA = Total Grade Points / Total Credit Hours |
How To Convert SGPA To Percentage?
To calculate the percentage from SGPA, you need to consider the grade point range and the corresponding percentage range established by your educational institution. The exact conversion formula may vary depending on the grading system used by your institution. However, we can provide you with a general method that is commonly used. Here are the steps to calculate the percentage from SGPA:
- Determine the grade point range and the corresponding percentage range for your institution.
- Determine your SGPA.
- Calculate the percentage using the below formula. In this formula, the Minimum Grade Point and Maximum Grade Point represent the grade point range established by your institution.
| Percentage = ((SGPA – Minimum Grade Point) / (Maximum Grade Point – Minimum Grade Point)) * 100 |
How To Convert Percentage To GPA?
To calculate GPA from a percentage, you need to consider the grade scale or grading system used by your educational institution. The exact conversion formula may vary depending on the grading scale. However, we can provide you with a general method that is commonly used. Here are the steps to calculate GPA from a percentage:
- Determine the grade scale or grading system used by your institution. This includes the grade points assigned to each percentage range.
- Determine your percentage.
- Find the corresponding grade point based on your percentage according to the grading scale.
- Calculate the GPA using the following formula. In this formula, Credit Hours represent the weight or credits assigned to each course.
| GPA = Sum of (Grade Point x Credit Hours) / Total Credit Hours |
