What is an SGPA To Marks Calculator?

In simple terms, a calculator is a tool used to calculate specific values through mathematical operations. Similarly, an SGPA to marks Calculator is a specially designed tool that converts your SGPA (Semester Grade Point Average) into percentage and marks. These conversions are particularly useful in education, especially when applying for scholarships, internships, further studies, or job opportunities where a percentage format is preferred or required.

Many universities and colleges follow a grading system based on SGPA, but real-world applications often demand a clear percentage score. That’s where this calculator comes in handy — offering a quick, reliable, and hassle-free way to bridge the gap between academic grades and practical requirements.

What is SGPA?

SGPA, or Semester Grade Point Average, is a grading system that reflects a student’s performance during a specific semester. It’s calculated based on the number of credit hours and the grade points obtained in each subject.

For example:

  • An A grade might equal 10 points,
  • B+ might equal 8 points, and so on.

The final SGPA is the weighted average of all your course grade points in a semester.

Elements of SGPA

To understand how SGPA is calculated and used, it’s important to familiarise yourself with its three fundamental components: Semester, Grade Points, and Credit Points.

1. Semester

A semester usually spans six months and represents half of an academic year. Dividing the academic calendar into semesters allows for more focused teaching and better understanding of each subject, as the syllabus is split into smaller, manageable portions.

2. Grade Points

Grade points indicate your academic performance in individual subjects. Each subject you study is evaluated and awarded a grade (like A, B, C), which is then converted into numerical grade points (like 10, 8, 6). The higher your grade, the better your score. These points play a key role in calculating your overall SGPA.

3. Credit Points

Credit points measure the weightage of a subject based on the number of instructional hours or effort required. Subjects with more credits require more learning time and contribute more to your final SGPA. To complete a semester, students must earn the necessary credit points by attending classes, submitting assignments, and passing exams.

How to Calculate SGPA?

Before converting SGPA into a percentage, you must first calculate your SGPA using the credit and grade points for each subject in a semester. Here’s a simple, step-by-step method:

Steps to Calculate SGPA

  1. List all the credit points for each subject in your semester.
  2. Multiply each credit point by its corresponding grade point.
  3. Add up the results of all these multiplications.
  4. Add all the credit points of your subjects together.
  5. Divide the result from Step 3 by the total from Step 4.
  6. The final result is your SGPA for that semester.

🎓 Example 1: Simple SGPA Calculation
SubjectCredit PointGrade
Subject P39
Subject Q28
Subject R38
Subject S27

Step-by-step breakdown:

  • Multiplications:
    3×9 = 27, 2×8 = 16, 3×8 = 24, 2×7 = 14
  • Total:
    27 + 16 + 24 + 14 = 81
  • Sum of credit points:
    3 + 2 + 3 + 2 = 10
  • SGPA:
    81 ÷ 10 = 8.1

Breakdown:

  • Multiplications:
    4×8 = 32, 3×8 = 24, 3×9 = 27, 2×7 = 14, 3×8 = 24, 2×7 = 14
  • Total:
    32 + 24 + 27 + 14 + 24 + 14 = 135
  • Total credits:
    4 + 3 + 3 + 2 + 3 + 2 = 17
  • SGPA:
    135 ÷ 17 = 7.94

SGPA Calculation Formula

You can also use the standard formula to calculate SGPA:

SGPA Formula:

SGPA (Si) = Σ (Ci × Gi) / Σ Ci

  • Si = SGPA for the semester
  • Ci = Credit for the subject
  • Gi = Grade for the subject

How to Convert SGPA To Marks?

After calculating your SGPA, the next step is converting it into marks or percentage, especially if you’re applying for jobs, scholarships, or higher studies. Most universities follow the UGC-approved formula for this conversion.


SGPA to Percentage (Marks) Formula:

Marks (%) = (SGPA × 10) – 7.5

This formula helps you understand your academic performance in terms of percentage, which is often more universally accepted than SGPA or grade points.


Example 1:
  • SGPA = 8.1
  • Calculation: (8.1 × 10) – 7.5 = 81 – 7.5 = 73.5%

Example 2:
  • SGPA = 7.94
  • Calculation: (7.94 × 10) – 7.5 = 71.9%

UGC-Approved Letter Grades & Their Meanings

As per University Grants Commission (UGC) guidelines, universities often represent performance using letter grades. Here’s how these grades translate into grade points and percentage ranges:

Percentage RangeLetter GradeGrade Points
90 – 100%O (Outstanding)10
80 – 89%A+ (Excellent)9
70 – 79%A (Very Good)8

How do you convert SGPA to marks?

To convert SGPA to marks (percentage), use the UGC-recommended formula:

Percentage = (SGPA × 10) – 7.5

For example, if your SGPA is 8.0:
→ (8.0 × 10) – 7.5 = 72.5%

How to find the total marks from SGPA?

SGPA itself doesn’t directly give you total marks. It reflects the weighted average of your grade points for a semester. However, to estimate total marks:

  1. Convert SGPA to percentage using the formula:
    (SGPA × 10) – 7.5
  2. Multiply the resulting percentage by your total maximum marks to get an estimate.

Example: If SGPA = 8.2 and your max total is 1000 marks:
→ (8.2 × 10) – 7.5 = 74.5%
→ 74.5% of 1000 = 745 marks

How much is 7.5 SGPA in percentage?

Using the same conversion formula:

(7.5 × 10) – 7.5 = 75 – 7.5 = 67.5%

So, 7.5 SGPA equals 67.5%.

How do you convert CGPA to marks?

To convert CGPA (Cumulative Grade Point Average) to percentage:

Percentage = (CGPA × 10) – 7.5

This is the same formula used for SGPA to percentage conversion, as recommended by UGC.

Example: If CGPA = 8.3
→ (8.3 × 10) – 7.5 = 83 – 7.5 = 75.5%
