What is GPA?Ā 

GPA (Grade Point Average) is a number indicating your average score in a single semester/unit or for the entire course duration. It is denoted by a number on a scale of 4 or 5.Ā 

This system of grading is more prevalent in international universities.Ā 

Note: The scale will shift on the basis of the grading system followed.Ā 

Hereā€™s how you calculate GPA:

GPA= Weighted Grade Points/Total Credit HoursĀ 

Courses Credit Hrs Grade Point for Grades Weighted Grade Pts.
Physics 4 A 4 4 x 4 = 16
Maths 3 B 3 3 x 3 = 9
English 3 B 3 3 x 3 = 9
Science 5 A 4 5 x 4 =20
Ā  Total = 15 Ā  Ā  Total = 54

Your Grade Point Average will be 3.6 (54 divided by 15).Ā

Indian universities use this system of assessment.Ā 

Based upon the CGPA system of assessment, specific grades are given for a range of scores. For example, 85-90 marks will have a Grade Point of 8.Ā 

Let us look at the table to understand how CGPA is calculated

Difference Between GPA and CGPA

The difference between GPA and CGPA is majorly in the fact that GPA, alongside measuring the overall performance, also measures performance in a single semester or unit while CGPA measures performance in the entire course (covering all semesters and units). The difference between CGPA and GPA can be understood through the following pointers:Ā 

  1. GPA may span a smaller duration, i.e. a semester or term while CGPA necessarily covers a longer time period like the entire degree/course duration (inclusive of all semesters).Ā 
  2. You should score a good GPA every semester to obtain a better average or CGPA in your degree course. GPA is thus linked to CGPA.Ā 
  3. International universities usually consider the GPAs of students for evaluating consistency in academic performance throughout any course. They often emphasize less CGPA.Ā 
  4. Universities in India make use of the 10-point CGPA grading system while the 4-point GPA method is used by universities in the UK and many others.

Importance of GPA and CGPA

Both GPA and CGPA are highly important for your academic journey and future prospects. Your GPA should remain consistent for you to get a good CGPA score. Colleges and universities will seek both your GPA and CGPA and you should emphasize both. Both GPA and CGPA will be displayed on your mark sheet, influencing your applications for higher studies abroad, placements and scholarships.Ā 

CGPA is vital for cut-offs at several scholarships and university courses. Students often fall short of the criteria by simple decimal numbers.Ā Hence, make sure that you strive for consistent GPAs throughout your course and an impressive CGPA at its conclusion.

How to Convert GPA into CGPA

Conversion from CGPA to GPA is done when students are applying to study abroad. Some universities have an internal process to get the grades converted according to their requirements. Some other universities ask students to get their grades evaluated by a recognized external agency and send them for admission consideration.Ā 

The difference between CGPA and GPA is simple. While GPA refers to scores obtained in a semester, CGPA measures the overall academic performance of a student i.e. the scores they have obtained in all the semesters combined.

As far as the conversions are concerned, foreign universities accept credential evaluation reports from external agencies only. These agencies need to necessarily be a part of NACES (National Association of Credential Services).Ā 

So, coming to the conversion of GPA to CGPA, the weighted average GPA (GPA x Credit hours) of a student across all semesters is divided by the sum of the credit hours.

For example,

Semester Credit Hours GPA Weight Average GPA
1 20 3 20×3
2 22 3.5 22×3.5
3 20 3.9 20×3.9

CGPA= Weight Average GPA/Total Credit Hours

215/62= 3.5

There are several third-party agencies that carry out these conversions for students.

GPA vs CGPA Conversion Table

4-point GPA to 10-point CGPA table is given below:

CGPA (10 Point) GPA (4 Point) Grade (4 Point Scale)
>8.5 >3.7 A
8.0 – 8.4 3.7 A
7.5 – 7.9 3.3 B+
7.0 – 7.4 3 B
6.5 – 6.9 2.7 C+
6.0 – 6.4 2.3 C
5.5 – 5.9 2 D+
5.0 – 5.4 1.7 D
<5.0 0 – 1.3 F

CGPA To Marks Conversion Formula

The conversion of CGPA to mark is a single-step procedure, meaning it needs basic calculation.

The formula for the same is % of marks= 9.5x CGPA.Ā 

If the CGPA is 8.5, the percentage will be 9.5×8.5= 90.25%
