What is an SGPA to Percentage Calculator?

In simple terms, a calculator is a tool used to find answers by doing basic mathematical calculations, and in the same way, an SGPA to percentage calculator is a special tool that helps convert SGPA (Semester Grade Point Average) into percentage easily. This type of calculator is mainly used by students in the education field to quickly understand their performance in percentage form without doing manual calculations.

What is SGPA?

The full form of SGPA is Semester Grade Point Average, and it is used by colleges and universities to measure a student’s performance in a particular semester. It shows the average grade points a student earns in all subjects during that semester, but not all institutions use the same system, which can sometimes create confusion. That is why students often need an SGPA to percentage calculator, as it helps them easily convert their SGPA into percentage and understand their academic performance in a more common and widely accepted format.

Elements of SGPA

For dealing with SGPA, you must have an idea of some basic elements like Semesters, Grade Points, & Credit Points.

Semester: The semester is of 6 months and academic years are usually divided into semesters for better & detailed learning of the course.
Grade Point: These points represent the performance of students in a specific subject learned during the course. These points are directly proportional to the knowledge of the students in that particular subject.
Credit Points: These points represent the dedication of students to a particular subject in terms of hours. Every student needs to spend a definite time period on each subject of the semester to earn qualifying credit points.

How to Calculate SGPA?

The results of each subject of a course are usually provided in terms of credit points. Students need to first calculate their SGPA for a particular semester from these credit points before converting them into percentages.

Here are some simple steps that can be followed to get SGPA value for a semester.

Step 1: Write down all the credit points for different subjects as mentioned in your performance sheet.
Step 2: Multiply the credit point of each subject with its grade point.
Step 3: Now, add the results of these multiplications for each subject.
Step 4: Add all the credit points for each subject.
Step 5: Divide the result of Step 3 by Step 4.
Step 6: The result obtained will be treated as your SGPA for the semester.

Example of SGPA Calculation

Example 1:

Subject	Credit	Grade
Subject P	3	9
Subject Q	2	8
Subject R	3	8
Subject S	2	7

Step 1: 3, 2, 3, 2
Step 2: 3 x 9 = 27, 2 x 8 = 16, 3 x 8 = 24, 2 x 7 = 14
Step 3: 27 + 16 + 24 + 14 = 81
Step 4: 3 + 2 + 3 + 2 = 10
Step 5: 81 / 10 = 8.1
Step 6: SGPA = 8.1

Subject	Credit Point	Grade
Subject I	4	8
Subject II	3	8
Subject III	3	9
Subject IV	2	7
Subject V	3	8
Subject VI	2	7

Step 1: 4, 3, 3, 2, 3, 2
Step 2: 4 x 8 = 32, 3 x 8 = 24, 3 x 9 = 27, 2 x 7 = 14, 3 x 8 = 24, 2 x 7 = 14
Step 3: 32 + 24 + 27 + 14 + 24 + 14 = 135
Step 4: 4 + 3 + 3 + 2 + 3 + 2 = 17
Step 5: 135 / 17 = 7.94
Step 6: SGPA = 7.94

Formula to Calculate SGPA from Grade Points & Credit Points

The steps mentioned to calculate the SGPA point from the grade points of each subject of a semester can be represented through a formula as mentioned below.

SGPA (Si) = Σ (Ci × Gi) / Σ Ci

In this formula, Si represents the SGPA for the ith semester, Ci represents the credit point of each subject in the ith semester, and Gi represents the grade point of each subject in the ith semester.

Formula to Calculate/Convert SGPA to Percentage

The formula used to get percentage values from SGPA points is provided here.

Percentage = (SGPA × 10) - 7.5

The above-mentioned formula can be divided into two steps for a simplified calculation:

Step 1: SGPA × 10

Step 2: (SGPA × 10) - 7.5

How to Convert SGPA to Percentage?

To get the overall result of your qualifying course in percentage, you first need to calculate the SGPA of all the semesters using the above-mentioned points. Add the SGPA points of all the semesters to get the overall SGPA point.

After you have the overall SGPA value, put it in the formula of SGPA to percentage conversion and get your performance grade in percentage value.

Example of SGPA to Percentage Calculation

For a better understanding of the students, they can see the examples provided here.

Example 1: SGPA = 8.1

Step 1: SGPA × 10 = 8.1 × 10 = 81
Step 2: (SGPA × 10) - 7.5 = 81 - 7.5 = 73.5%

Example 2: SGPA = 7.94

Step 1: SGPA × 10 = 7.94 × 10 = 79.4
Step 2: (SGPA × 10) - 7.5 = 79.4 - 7.5 = 71.9%

Letter Grades Approved by UGC

As per the UGC guidelines, letter grades are also being used by many institutions or universities that represent a particular grade point and a range of percentages. The accepted Letter Grades with their corresponding Grade Points & Percentage range are listed below.

Percentage of Marks	Letter Grade	Grade Points
90–100%	O (Outstanding)	10
80–90%	A+ (Excellent)	9
70–80%	A (Very Good)	8
60–70%	B+ (Good)	7
50–60%	B (Average)	6
40–50%	C (Pass)	5
Below 40%	F (Fail)	0
Absent	AB	0

Difference Between SGPA and CGPA

CGPA is the abbreviation of Cumulative Grade Point Average and it represents the performance of a student in an academic year. While SGPA is the performance grade for a semester. CGPA can be calculated from SGPA after adding up all the SGPA values of each semester and then dividing it by the sum of the number of semesters.

For example, if the SGPA of a student in his 1st and 2nd semester is 6 and 8, respectively, then the CGPA will be calculated as:

CGPA = (SGPA of Semester 1 + SGPA of Semester 2) / (Sum of Semesters)

= (6 + 8) / (1 + 1)

= 14 / 2

= 7

Another difference between CGPA & SGPA is that CGPA is used as a performance grade method at the school levels while SGPA is used in higher studies.
