Convert SGPA to percentage


If you are looking for an SGPA to percentage calculator, you can make use of the given SGPA to percentage converter. By entering the SGPA in the given space, you will be receiving the corresponding percentage. 

With the advancement in the education system, the universities across the globe are adapting to the grading system of scoring. The calculation methods may differ based on the universities but the SGPA, CGPA, GP, and percentage calculations are mostly the same. You must understand the SGPA to percentage calculation to know how your academic performance is evaluated. 

Educational institutions have started using their own SGPA to percentage calculators for their student's convenience. In this article, we will be discussing the SGPA to percentage conversion process, the formula used, the terms involved, CGPA calculation, SGPA calculation for different universities, etc. 


What is SGPA?

The Semester Grade Point Average (SGPA) is used to indicate a student's performance in a year or a semester. SGPA is defined as the weighted average of the grade points secured by the student in each subject registered during the particular semester. The SGPA range differs between 0.00 and 10.00 based on student performance and an SGPA calculator can be used to calculate the value. 

SGPA is accepted and used by most educational institutions in India and worldwide. These institutions also use an SGPA to percentage calculator or converter to indicate the student's skill level in percentage. You must perform well in the exams to secure a good SGPA which in turn will lead to a good CGPA.  

How to calculate SGPA?


To calculate SGPA you must know your grade points obtained per subject, the individual subjects' credit points, and the total number of subjects you have appeared for. The SGPA calculator can be used to easily find the SGPA value. Learning how to calculate SGPA is essential as it reflects on your performance in a particular semester or a year. There are several ways to calculate your SGPA, but let's discuss the simplest way to calculate SGPA. 

  • Write the allotted credit points for each subject in a row. 
  • Note down the grade you have obtained against each subject. 
  • Now multiply the credit points and the grade point for each subject. 
  • Add all the resulting values obtained from the previous step. 
  • Then, divide the obtained total score by the sum of all the credit points. 
  • The final value will be your SGPA ranging between 0-10. 

For a better explanation of SGPA calculation, you can follow the given sample of SGPA calculation for a 4 subject semester. 

The credit points for the 4 subjects will be as:

  • Subject 1 - 3
  • Subject 2 - 4
  • Subject 3 - 3
  • Subject 4 - 5

The grades obtained on these subjects are:

  • Subject 1- A
  • Subject 2 - O
  • Subject 3 - B
  • Subject 4 - A+

The following table will show the grade points for the respective grades. 

Marks Range(Out of 100) Description Grade Grade Points
90-100 Outstanding O 10
80-89 Excellent A+ 9
70-79 Very Good A 8
60-69 Good B+ 7
50-59 Above average B 6
40-49 average C+ 5
35-39 Pass  P 4
0-34 Fail F 0
Otherwise Absent - -

Now multiple the obtained grades with the credit scores.

  • Subject 1 - 8*3 = 24
  • Subject 2 - 10*4 = 40
  • Subject 3 - 3*6 = 18
  • Subject 4 - 5*9 = 45

Next find the summations of the credit scores and the multiplicated values 

Credit score sum- 3+4+3+5 = 15
Total score - 24+40+18+45= 127

SGPA = 127/15 = 8.44

You can use the below-given table to understand the calculation better 


SGPA = Sum of grade points / Sum of credit points 
             = 127/15 = 8.44

How to convert SGPA into percentage?

The steps followed in converting SGPA to percentage are as follows, 

  • Calculate the SGPA using the manual calculator or the SGPA calculator. 
  • Next subtract the SGPA by 0.75 
  • Multiply the answer by 10. 
  • The derived answer will be your percentage. 
  • If you are calculating your percentage for your complete course duration, you need to add the SGPA for all the semesters and divide the sum by the total number of semesters. The result will be your overall SGPA. 

Formula to convert SGPA to Percentage

To convert SGPA into percentage, you can use the simple formula, 

Percentage = (SGPA - 0.75)*10 
                      (SGPA *10)-7.5 

For instance, if your SGPA is 8.5 then your percentage can be calculated as follows. Subtract 0.75 from 8.5. This would be 7.75. Now multiply 7.75 with 10. Thus your percentage would be 77.5. 

Percentage = (SGPA-0.75)*10 
                  = (8.5-0.75)*10 = 77.5%

What is CGPA?

Cumulative Grade Point Average (CGPA) is the grading system accepted by educational institutions across the globe to offer admission. The CGPA is the educational grading system used to measure a student's performance over an academic tenure. Different countries have their own grading system which can be an alphabet, percentage, number, or range that will indicate the student's educational performance. 

The CGPA is obtained by dividing the mean grade points by the number of semesters. The CGPA can be calculated for a particular period of time or an academic year like 1st year or 2nd year. 

The table below may give an insight into the basic CGPA calculation based on percentage


How to convert SGPA to CGPA?

The SGPA being the cumulative grade point of a particular semester, the CGPA can be easily calculated from the SGPA. The mean value of the SGPA over a period of education gives you the CGPA. 

For instance, if the SGPA for 3 semesters is 7, 8, and 5, then the CGPA will be calculated as follows. 

CGPA = (Total sum of SGPA) / total number of semesters 
         = (7+8+5)/(3)
         = 6.66

Difference between SGPA and CGPA

The main difference between the SGPA and CGPA is that SGPA is the mean value of the grade points obtained per semester, whereas CGPA is the cumulative grade points obtained in an academic year. The sum of SGPA will give the CGPA. Thus for a good CGPA, you must have a perfect SGPA each semester. Both terms are used to reveal the student's academic performance. 

Common terms and meanings used in SGPA to percentage calculation

To understand how to calculate percentages from SGPA, you must be aware of the terms involved in the SGPA calculation. Knowing these terms will help you in cross-checking your values, even after using the SGPA to percentage calculator. The terms are as follows,


The course tenure of your education is divided into small segments known as semesters. In one academic year, there will be two semesters. For instance, in engineering courses, there are a total of 8 semesters in 4 years. 

Credit points

The study load of a subject is measured as credit points. The credit points will be assigned by the universities based on the hours spent on the particular course during the semester. The educational system assesses your progress and completion of the course based on the credit points received. 

Grade points

You will be awarded a grade based on the marks obtained in that particular subject. Each grade will be having its corresponding grade points with which the overall performance of the student in a particular subject will be determined. 

How to calculate SGPA from marks?

  • If marks are given, write the marks and note down the corresponding grades. 
  • From the grades obtained, identify the grade points. 
  • Now multiply the grade points by the corresponding subjects’ credit points. 
  • Next add all the values to receive the total grade points. 
  • To calculate the SGPA, divide the total grade points by the sum of all the credit points. 
  • To obtain the percentage from SGPA, you can use the formula (SGPA-0.75)*10.

How to calculate SGPA in engineering?

The SGPA for an engineering course is calculated using credit points and grade points. Usually, the engineering results are represented in SGPA, CGPA, and percentage. The SGPA will be calculated per semester and the CGPA will be calculated for the entire academic tenure. The SGPA to percentage converter can be used to calculate the student's performance in percentage.

How to calculate SGPA in Mumbai university

The University of Mumbai is using two types of grading system, a 7-point grading system, and 10 point grading system. For the 7-point grading system (CBGS), the percentage will be calculated based on the actual marks obtained by the students in each subject. The percentage of the 10-point grading system will be calculated using the following formula, 

Percentage = 7.1* CGPA +11

Thus the SGPA to percentage Mumbai University conversion process is as follows. First the individual semester SGPA will be calculated, then CGPA will be derived using the SGPA and finally converted into percentages using the formula. 

How to convert SGPA to CGPA to Percentage?

For easy understanding, here you will be seeing how the SGPA to percentage calculation works from an example. 

Semester 1:

Subject Grade Grade points(GP) Credit points(CP) GP*CP
1 A+ 9 3 27
2 B+ 7 3 21
3 O 10 4 40
4 C 5 3 15
Total     13 103

SGPA for semester 1 = (GP*CP)/ (Sum of CP)
    = 103/13 = 7.92

SGPA to percentage for Semester 1= (SGPA *10)- 7.5
                    = (7.92*10)-7.5 = 71.7%

Semester 2:

Subject Grade Grade Points(GP) Credit Points GP*CP
1 A 8 4 32
2 A+ 9 4 36
3 B 6 2 12
4 B+ 7 2 14
Total     12 94

SGPA for semester 2 = (GP*CP)/ (Sum of CP)
    = 94/12 = 7.83

SGPA to percentage for Semester 1= (SGPA *10)- 7.5
                    = (7.83*10)-7.5 = 70.83 %

CGPA = (SGPA for semester 1 + SGPA for Semester 2) / 2
    = (7.92+7.83) / 2
    = 7.875
