CGPA Calculation for Engineering Students – Formula, Advantages, Examples | How to Calculate CGPA?

CGPA Calculation for Engineering Students

CGPA Calculation for Engineering Students: All of us have heard the term CGPA many times in our life and have wondered what it meant. Nowadays, most engineering colleges follow the CGPA system as it is a globally recognized system as it assists a person in understanding where they stand in comparison to their classmates.

Many colleges nowadays demand that students produce their cumulative averages during the entrance process. Here, we have a guide on how to calculate CGPA in engineering if you want to get admitted to one of the engineering branches.

What is CGPA?

CGPA refers to ‘Cumulative Grade Point Average.’ It is used to denote a student’s total average performance throughout their academic programs. CGPA is accepted in a high school, Bachelor’s Degree and also in Master’s Degree programs.

The CGPA system is one of the most common evaluation ways, even though the criteria might vary from one country to another. So, it is essential to understand how to calculate CGPA in engineering. CGPA is the total of all your credit points.

Advantages of CGPA

There are various benefits of calculating CGPA, so you should be aware of how to calculate CGPA in engineering. Here are some of the benefits of having the CGPA system of evaluating and grading your results:

  • The pressure of marks reduced: The grading standard of education has decreased students’ scoring pressure, which in turn makes them learn without any pressure.
  • Identification of Strengths and Weakness: The grading standard of education helps students identify their strengths and weaknesses.
  • Grading Pattern is advanced: The grading standard of education is based on a progressive marking pattern.
  • Studies become simpler: The grading standard of education has made education more straightforward and more accessible in various ways.
  • It also helps the colleges and universities accurately analyze where one stands in comparison to the other students.

How to Calculate CGPA in Engineering?

To calculate CGPA, the students also need to know about the GPA- Grade Point Average. The value represents the average value of the accumulated final grades scored in courses over time. This means that all of your grades are combined altogether, and then they are divided by the total subjects you had in that semester. Engineering students can also convert CPI to a percentage, CGPA to a percentage, and CGPA to marks to get clarity.

CGPA = total of GPA in all semesters/ Total Number of Credit Hour

If you are thinking about how much CGPA you should score to be considered as good CGPA in engineering, the CGPA of 8 or above is usually considered the best. As the competition for studying abroad can be extreme, one should aim for a slightly higher CGPA.

How is CGPA Calculated in India?

As the CGPA grading system varies from one country to another, the Indian grading system that is CGPA to percentage conversion differs from other countries and varies from one university to another. Here, we have laid out the general way to calculate CGPA in Engineering or any other courses in India:

CGPA = Percentage/9.5

For instance, the total marks you score in a total of five subjects in a particular semester add up to 250.

How TO Calculate CGPA in University

Step 1: At first, you need to calculate the total percentage you got, that is,

250/500 = 50%

Step 2: Then, you need to calculate the CGPA from percentage; you need to divide your percentage by 9.5 that is,

50/9.5= 5.26 CGPA approximately.

CGPA Calculation

How to Calculate SGPA?

A student’s performance in a semester is indicated by a number called the Semester Grade Point Average or SGPA. The SGPA is a weighted average of the grade points obtained in all the courses, projects, and seminars registered by the student. It can be calculated by simply adding up all the credit points allocated for the subjects and dividing it by the total credits awarded to that semester.

For instance, in a total of 4 subjects, one scored the following grade points:

Subject 1: 9

Subject 2: 6

Subject 3: 8

Subject 4: 7

Let’s say that the total credit for each subject is 10.

Step 1: At first, we will multiply the grade point with the total credit point for each subject:

Subject 1: 9 * 10 = 90

Subject 2: 6 * 10 = 60

Subject 3: 8 * 10 = 80

Subject 4: 7 * 10 = 70

Step 2: To calculate SGPA here, you need to get the total of all the grade points and then divide it by the total credits, that is,

Total grade points: 310

Total credits: 40

To get SGPA, divide the grade points by total credits,

= 310 / 40

= 7.75 SGPA

How to Calculate CGPA from SGPA?

After the universities release the results in the form of CGPA, one still has to convert that CGPA to a percentage if you want to pursue your further studies in a foreign country, as there shall be the requirement for the scores to be in percentage.

Because of this reason, we have given out the pathway of transforming your CGPA to a percentage:

  • At first, you need to find the SGPA of all the semesters.
  • Once you have the SGPA of all the semesters, add them.
  • Divide the addition of the SGPAs by the Number of the semester you have given.
  • The Number you get is your CGPA.

For instance, the SGPA of a student for six semesters is,

  1. Semester I: 8.0
  2. Semester II: 7.0
  3. Semester III: 7.4
  4. Semester IV: 6.8
  5. Semester V: 7.8
  6. Semester VI: 7.2

Add all of the SGPA, i.e.,

8.0 + 7.0 + 7.4 + 6.8 + 7.8 + 7.2 = 44.2

Divide the addition by the Number of semesters, i.e.,

44.2 / 6 = 7.37 (CGPA).

How do the Engineering Colleges Abroad Award/ Calculate CGPA / GPA?

Generally, to calculate the SGPA, candidates have to multiply by 10. On the other side, CGPA is calculated with the assistance of credit points. Let us understand how to evaluate CGPA in engineering with the support of an example.

Example: The following scorecard represents the credits and grades scored by a student in a semester. Let us be aware of the process of calculating CGPA in a specific semester.

Subjects Grade Credits
Subject 1 A 2
Subject 2 B 2
Subject 3 B 4
Subject 4 B 4
Subject 5 B 4
Subject 6 B 5
Subject 7 A 3
Subject 8 S 4

Average Overall grade: 8.04

Where the grading scale is,

S: 10, A : 8.5, B : 7.5, C : 6.5, D : 5.5, E : 4.5

For each subject, the students are awarded credit and a grade. We multiply the credits with the grades’ allocated score points and divide the result by the total number of credits to get the SGPA. In this case, SGPA is, = 8.04

Now coming on to how to calculate CGPA, it is nothing but the average of all the SGPAs. You can add the SGPA earned in each semester and divide them by the total number of semesters. CGPA can either be calculated out 4 or 10, depending on the university. Let’s say that a person gets the following SGPAs in 6 semesters:

Semesters SGPA
I 7
II 8
IV 8
V 6
VI 5

In this case, the CGPA for the course be: = 7.17

One should also note that CGPA can be obtained out of 4 or 10 depending upon the educational university system. Out of 10 can be altered to out of 4 by efficiently dividing the subtotal by ten and multiplying it by 4.

One can also calculate their CGPAs or percentage by calculating the Percentage CGPA calculator for engineering for which you need to know your CGPA (for percentage) or percentage (for CGPA).

How do the Indian Engineering Colleges Calculate CGPA?

There are two ways used when we talk about the evaluation system that is used in India, namely the Relative and Absolute Grading System. Although the latter is the total percentage obtained irrespective of how many students score the same marks, the former highlights the student’s performance compared to others. We have given an example to help you understand how to calculate CGPA in engineering through the relative grading system.

Let’s say that the marks out of 100 are allocated to a certain bracket of grades and numeric values. These are put in a table form below:

Grades Numeric Value
A+ 10
A 9
B 8
C 7
D 6
E 5
F 0

Like we already stated, SGPA is first evaluated, and then the final CGPA is calculated. Following this logic, if we consider that chemistry and maths are awarded a total of 4 credit points each by your university. Thus, the marks and the grade point as per the table given award will be:

90-100 is a ten that is an A+

80-89 is a nine that is an A

70-79 is an eight that is a B

And so on.

So, if someone scores 78 in their chemistry and 98 in their maths, they will get an eight and a 10 for chemistry and maths, respectively. Their CGPA will be:

(The credit allotted to the subject * the point received) / The total credit points

=  =  =  = 9

The final step in calculating CGPA in Engineering can be done through a statistical method. Let us consider that there is X number of students in a class. Students’ means can be denoted by Y and Z and can be known as the standard deviation. Then,

Lower Range of Scores GRADES Upper Range of Scores
A+ > (Y + 1.5 Z)
(Y + 1.0 Z) < A Less than equal to (Y + 1.5 Z)
(Y + 0.5 Z) < B+ Less than equal to (Y + 1.0 Z)
Y B Less than equal to (Y + 0.5 Z)
(Y – 0.5 Z) < C+ Less than equal to Y
(Y – 1.0 Z) < C Less than equal to (Y – 0.5 Z)
(Y – 1.5 Z) < D Less than equal to (Y – 1.0 Z)
F Less than equal to (Y – 1.5 Z)

Understanding GPA and Calculating It

GPA (Grade point Average) is a widely known and internationally recognized calculation method for academic marks. Simple, the average or aggregate score of the grades cumulated during the entire duration of any course or program for a fixed period. The GPA system allows any person to read the individual results quickly and efficiently and analyze them compared to others’ results. It is also helpful for people to access their applications and reflect their academic potential and capabilities.

Generally, GPA is calculated by dividing a student’s average grade by the total credit hours that they attended during the fixed period of an academic course or program. The formula for GPA calculation is as follows:

GPA = Total grade points / the Total number of credit hours for a selected course’s fixed period.

Converting Percentage to GPA

GPA and Indian Grading System

In contrast to the GPA grading system, which is prominent in the USA and various other nations globally, the Indian grading system considers two main approaches, i.e., a 10-point GPA system or the percentage system. Here is a brief on both the systems prominently used across several Indian institutions and education boards.

Percentage System

Coming over the percentage method, this is the more preferred evaluation mechanic. In this grading system, the marks for a specified duration are converted to a percentage, and the ranks are then classified as follows:

  • 75% = Distinction
  • 60% – 75% = 1st Division
  • 50% – 60% = 2nd Division
  • 40% – 50% = 3rd Division

GPA System

In GPA out of 10 scales, points associates with letter grades for marking the students. For example, if the grade point is 9, the student’s grade will be “A”. This grading system is also quite akin to the international grading system with a 4.0 scale. For example, if a student scores 95%, the result for him/her will be as an A grade, meaning 4.0; 85% would equal to B grade, meaning 3.0; and C grade is 2.0 and D is 1.0.

Conversion of the Percentage to GPA

While considering the USA education system, the students get a rating either out of 0 – 4.0 grade points or follow the 10-point GPA system. Many of the prominent European universities also follow the 10-point GPA system. In specific scenarios, various institutes have different ways of converting percentage to GPA out of 10. The most prominent and widely used and accepted method is multiplying or dividing the score by 9.5 to convert it into percentage or GPA, respectively.

Converting Percentage to GPA for 4.0 Scale

While considering the US grading approach, there is a prominent usage of the 4.0 GPA scale, meaning that if we compare it to the Indian grading system of the percentage that is of 100 (100 points), 25 points in this system equals 1 point in the US GPA grading system. Thus, the formula for converting Percentage to GPA on a 4.0 scale is for merely doing the division of the percentage by 100 and then multiplying the same to 4. Here is the formula for the percentage to GPA converter:

GPA = (percentage/100) * 4

This conversion mechanic is also widely used for doing the GPA to percentage conversion.

Example: Suppose any student scores 70% as the aggregate score in the graduation; while preparing the application for any prominent US-based institute, he/she will have to put the graduation scores in GPA. This the students can calculate by dividing 70% by 100 and then multiplying it by four, and this will make the grade point as 2.8 GPA.

Converting Percentage to GPA for 10.0 Scale

Apart from India, many other nations also use a 10-point GPA system in various schools and institutes. For converting percentage to GPA out of 10, the student can just multiply the percentage by 9.5. The calculation formula for the percentage to GPA conversion is as follows:

GPA = Percentage/ 9.5

Example: If a student secures 85% in any examination, then while applying for any US-based university, the application form might have a field to be filled with the scores in the form of GPA. Thus by converting GPA out of 10, the person who access the application form gets ease in comparing the scores with the other students who graduated from other schools in the USA or any other part of the World. For converting percentage to a 10GPA, the student must divide the percentage secured that is 85%, by 9.5, and the GPA will come out to be 8.9.

A Brief Explanation On GPA Out Of 10 Scale

The GPA scale varies from 0-10, and here 0 means a failure in the test/exam, and 10 means excellent academic results. Here is a brief description of how to analyze the performance of any student in the 10-point GPA grading system:

Score Details
9-10 Excellent
7.5-8.99 Good
6-7.49 Average
5-5.99 Needs some improvement
0-4.99 Fail

GPA to Percentage Conversion

The widely used formula for GPA to percentage conversion is as follows:

Percentage = GPA * 9.5

For example, if a student has a GPA of 8, multiplying it with 9.5 will give the percentage, i.e., 8 * 9.5 =76%

Must Check: CGPA Calculation for Engineering Students

FAQ’s on Converting Percentage to GPA Out of 10

Question 1.
Calculate GPA of 70%.

While considering the 4.0 grading scale, 70% will equal to (70 / 100) * 4, i.e., 2.8 GPA.

And while considering the 10 point grading system, 70% will be converted to GPA as 70 / 9.5 = 7.36.

Question 2.
What is my GPA while considering a 4.0 scale?

In a 4.0 GPA grading system, a 4.0-grade point accounts for an A+ or A, followed by 3.0, which accounts for B, 2.0 for C, and 1.0 for D.

If the grade has a plus following it, this means that the student scored an additional one-third of a point, like B+ = 3.3.

On the other hand, if a minus follows the grade, the student scored one-third less than the grade point, like A- = 3.7.

Question 3.
How do we convert percent to GPA?

Two main scales are widely standard for converting percentage to GPA, either on a 4.0 scale or on a 10.0 scale. 4.0 scale grading system is widely popular across the university and institutes of the US, while a 10 GPA scale is standard across India.

For converting percentage to GPA on a 4.0 scale grading system, one must divide the percentage scored by 100 and then multiply the resultant by 4 to get the GPA. Here is the formula for converting percent to GPA on a 4-scale:

GPA on 4.0 scale = (Percentage / 100) * 4

For converting percentage to GPA on a 10.0 scale, one must divide the percent by 9.5, i.e.,

GPA on 10.0 scale = Percentage / 9.5

Conclusion on Converting Percentage to GPA Out of 10

Conversion of the percentage to various GPA points and vice versa plays a crucial role while submitting multiple applications according to different universities and institutes from across the World.

Question: Find the inflection points for the function f(x) = -x4 + 6x2?


Given function is f(x) = -x4 + 6x2

f'(x) = -4x3 + 12x

f”(x) = -12x2 + 12

f”'(x) = -24x

f”(x) = 0

-12x2 + 12 = 0

12 = 12x2

Divide by 12 on both sides.

1 = x2

x = ± 1

x1 = 1, x2 = -1

Substitute x = ± 1 in f”'(x)

f”'(1) = -24(1) = -24 < 0, then it is left hand bit to right hand bi.

f”'(-1) = -24(-1) = 24 > 0, then it is left hand bit to right hand bit.

Replace x = ± in f(x)

f(1) = -1+6 = 5

f(-1) = -1 +6 = 5

Therefore, inflection points are P1(, 5), P2(-, 5)

FAQs on Inflection Point Calculator

1. How do you find inflection points on a calculator?

Provide your input function in the calculator and tap on the calculate button to get the inflection points for that function.

2. What does inflection point mean?

Inflection point is defined as the point on the curve at which the concavity of the function changes. It can be a stationary point but not local maxima or local minima.

3. Find the point of inflection for the function f(x) = x5 – 5x4?

Given that

f(x) = x5 – 5x4

f'(x) = 5x4 – 20x3

f”(x) = 20x3 – 60x2

f”'(x) = 60x2 – 120x

Neccessary inflection point condition is f”(x) = 0

20x3 – 60x2 = 0

20x2(x-3) = 0

x1 = 0, x2 = 3

Substitute x2 = 3 in the f(x)

f(3) = 35 – 5*34 = 243 – 405 = -162

Inflection Point is (3, -162).

4. What is the difference between inflection point and critical point?

A critical point is a point on the graph where the function’s rate of change is altered wither from increasing to decreasing or in some unpredictable fashion. Inflection point is a point on the function where the sign of second derivative changes (where concavity changes). A critical point becomes the inflection point if the function changes concavity at that point.

Question1: Solve Lim x->5 x^2-6x+8 / x-4?


Here we use the substitution method

f(x)=x^2-6x+8 / x-4

f(5) = 5^2 – 6*5 + 8 / 5-4 = 25-30+8 / 1 = 3

Therefore, the solution is 3.

Question2: Solve lim x->4 x^2-6x+8 / x-4?


f(x)=x^2-6x+8 / x-4

Substitution process does n’t work here. Because the denominator can’t be zero.

Check out the factorization method

After factorization the f(x) can be as follows

f(x) = (x-4) * (x-2) / (x-4)

After cancelling f(x) = x-2

f(4) = 4-2 = 2
