How to Convert SGPA to CGPA?

According to the definitions we have established of SGPA and CGPA, CGPA can be termed as the collective SGPAs calculated at the end of an academic year. To calculate your CGPA, you need to first find the average score of all subjects in each of the semesters, i.e. SGPA. Then, add all the SGPAs of all the semesters and divide the total by the number of semesters or sessions to find your CGPA for the academic year.

CGPA= (SGPAs of All semesters in an academic year)/Number of semesters

For example:
If a student scored 8 and 7 SGPA in their two semesters, their CGPA would be:

CGPA of 1 college academic term = (SGPA of semester 1+ SGPA of semester 2)/ 2
= (8+7)/2
= 15/2= 7.5 CGPA

Now that you are through with the formula of converting SGPA to CGPA, let us understand how we can find out the percentage through similar formulas.

[(SGPA * 10) – 7.5 = Percentage]

For example: 
SGPA of a student for 4 semesters= 7.0, 6.9, 7.1, 6.8
= 7.0 + 6.9 + 7.1 + 6.8 = 27.8 
= 27.8/ 4 = 6.9
= (6.9 x 10) – 7.5 = 69- 7.5 = 61.5 %

What is SGPA? 

SGPA is the abbreviated form of Sessional Grade Point Average/Semester End Grade Point Average. Before delving into the discussion of SGPA and CGPA, let’s first understand what these two mean. To begin with, the marks we score in our schools or colleges can be calculated in different ways. One of these ways includes SGPA. It is the grade point average that is calculated at the end of an academic session like a year at school or a semester at college. First, the grade points of all the subjects in an academic year or session are collected together and then their average is calculated which is referred to as the SGPA for that particular year or session.

What is CGPA?

Another prominent method of calculation of the marks we score in our colleges or schools is through CGPA. Simply put, CGPA is the abbreviated form of Cumulative Grade Point Average and depicts the total marks we score in a complete academic term or a certain period like the 1st year or 3rd year of college. The total marks that we score in all the sessions of a college term or both half yearly examination in school, is taken together to calculate the CGPA scored in that academic term.

The central difference between sessional grade point average and cumulative grade point average is that we calculate CGPA at the end of the academic year with many SGPAs of different semesters or sessions. Students must understand that having an idea about what is CGPA will help them get a hold of how to calculate SGPA.

Now that you know what SGPA, CGPA and GPA are, let’s try to find out the key differences between these concepts.

  • CGPA as the cumulative GPA is a result of the division of the sum of all the SGPAs in an academic year with the number of semesters. So, in simple terms, CGPA is calculated for the entire course while GPA is per the semester and SGPA is for a particular session be it a year or so. 
  • Many universities and colleges have different grade systems some use GPA while others have CGPA as the major grading system to assess the scholastic abilities of a student.
  • While CGPA and GPA aim to highlight a student’s academic performance over a stipulated period, many institutions prefer GPA more than CGPA to give admissions to students.
  • CGPA is reflective of your performance for an entire course thus it can only be a higher one if you have a better GPA and SGPA. Another prominent difference is that CGPA and SGPA always differ from the scale of 0.0-10.0/

How to Calculate SGPA?

Once you have understood what SGPA essentially is, the next step is to learn how it can be calculated. Semester Grade Point Average (SGPA) essentially reflects a student’s performance over a stipulated period, generally a semester. To find out your SGPA, you need to take all your credit points obtained in a semester and then divide the sum by the total credit points of the semester.

Here are the pointers explaining how you can calculate SGPA-

  • First, multiply the credit points of each subject by the grade points you have earned in the subject. 
  • Then, add all the total grade points you have got.
  • Now, divide this sum by the total sum of credit points for the semester. You will get your SGPA.

To understand it with an example, let’s say you have three subjects in a semester, and you have scored the following grade points, 

Subject 1: 8; Subject 2: 6 and Subject 3: 7

Now, suppose the credit points for these subjects are:

Subject 1: 3; Subject 2: 4; Subject 3: 4

First, multiply your grade points with their respective credits:
Subject 1: 8*3= 24
Subject 2: 6*4= 24
Subject 3: 7*4= 28

Now, add these grade points you have got: 24+24+28= 76 as well as add all the credit points, i.e. 3+4+4= 11

To get your SGPA, simply divide the total sum of grade points by the sum of credit points, 
= 74/11
=6.72 SGPA


How CGPA is calculated from SGPA?

To calculate the CGPA from SGPA one needs to add up the SGPA for all the semesters and divide the sum by the number of semesters. The obtained number is your CGPA. 

Is SGPA and CGPA same?

No, SGPA and CGPA are not the same. SGPA is the grade point received in a particular semester, whereas, CGPA is the overall grade point of a candidate.

What is SGPA and CGPA in college?

CGPA means Cumulative Grade Point Average and is the measuring grade for your overall performance during an academic year while SGPA is a Semester Grade Point Average that adds all the CGPAs together after an academic program.

How much is 9.8 CGPA in percentage?

9.8 CGPA would be 93%.

The calculation of our academic performance through SGPA to CGPA is an easy process and helps in maintaining healthy competition among students where the focus is more on learning than trying to score the highest.
