Convert your marks to SGPA with precision and ease
Your marks will be converted using the following grading criteria:
Your SGPA
Converting your semester marks to SGPA can feel confusing, especially when you’re dealing with different credit hours and grading systems. This comprehensive guide will walk you through everything you need to know about calculating SGPA from your marks, including step-by-step formulas and practical examples.
SGPA stands for Semester Grade Point Average. It’s a numerical representation of your academic performance in a specific semester, calculated based on the grades you earn in each subject and their respective credit hours.
Grade Points: Each letter grade (A+, A, B+, B, etc.) corresponds to a specific numerical value:
Credit Hours: The weightage assigned to each subject based on its importance and class hours per week. Core subjects typically have 3-4 credits, while lab subjects may have 1-2 credits.
Why SGPA Matters: Universities use SGPA to evaluate your semester performance, determine scholarship eligibility, and calculate your overall CGPA (Cumulative Grade Point Average).
Step 1: Convert Marks to Grade Points
First, you need to convert your percentage or marks into grade points using your university’s grading scale.
Common Grading Scale:
Marks Range | Grade | Grade Points |
90-100% | A+ | 10 |
80-89% | A | 9 |
70-79% | B+ | 8 |
60-69% | B | 7 |
50-59% | C+ | 6 |
40-49% | C | 5 |
35-39% | D | 4 |
Below 35% | F | 0 |
Step 2: Apply the SGPA Formula
SGPA Formula:
SGPA = (Sum of Grade Points × Credit Hours) ÷ Total Credit Hours
Step 3: Practical Example
Let’s calculate SGPA for a student with these subjects:
Subject | Marks | Grade Points | Credit Hours | Grade Points × Credits |
Math | 85% | 9 | 4 | 36 |
Physics | 78% | 8 | 3 | 24 |
Chemistry | 92% | 10 | 3 | 30 |
English | 65% | 7 | 2 | 14 |
Lab | 88% | 9 | 1 | 9 |

Manual Calculation Worksheet
If you prefer calculating manually, use this template:
Subject Name | Marks (%) | Grade Points | Credit Hours | Points × Credits |
Subject 1 | ___ | ___ | ___ | ___ |
Subject 2 | ___ | ___ | ___ | ___ |
Subject 3 | ___ | ___ | ___ | ___ |
Total | — | — | ___ | ___ |
Final SGPA = Total (Points × Credits) ÷ Total Credit Hours
Many students need to convert their SGPA back to percentage for job applications or further studies.
Common Conversion Formulas:
Method 1 (Most Universities):
Percentage = (SGPA × 10) – 7.5
Method 2 (Some Technical Universities):
Percentage = SGPA × 9.5
Conversion Table:
SGPA | Percentage (Method 1) | Percentage (Method 2) |
10.0 | 92.5% | 95.0% |
9.0 | 82.5% | 85.5% |
8.0 | 72.5% | 76.0% |
7.0 | 62.5% | 66.5% |
6.0 | 52.5% | 57.0% |
Important Note: Always check your university’s official conversion formula, as methods can vary between institutions.
What If You Have a Backlog or Failed Subject?
Backlogs and failed subjects significantly impact your SGPA calculation. Here’s how to handle them:
Impact of Failed Subjects:
Failed Subject (F Grade):
Example with Backlog:
Subject | Grade Points | Credit Hours | Points × Credits |
Math | 8 | 4 | 32 |
Physics | 9 | 3 | 27 |
Chemistry | 0 (Failed) | 3 | 0 |
English | 7 | 2 | 14 |
SGPA = (32 + 27 + 0 + 14) ÷ (4 + 3 + 3 + 2) = 73 ÷ 12 = 6.08
Strategies for Improvement:
SGPA measures performance in one semester, while CGPA is the average of all semesters completed. CGPA = (Sum of all SGPA × Credits) ÷ Total Credits.
No, SGPA is fixed once grades are finalized. However, you can improve your overall CGPA in subsequent semesters.
Most online calculators are accurate if you input correct data and use the right grading scale. Always verify with your university's official method.
Grading scales vary by institution. Check your university handbook or academic office for the specific grade point system used.
Yes, 8.0 SGPA is generally considered good performance, equivalent to about 72-76% depending on conversion method.
Use the same formula but ensure you're using the correct credit hours for each subject as specified in your curriculum.
Yes, typically theory subjects have 3-4 credits while lab subjects have 1-2 credits, depending on contact hours.
Audited courses don't count toward SGPA calculation as they don't carry grade points or affect your academic standing.
Understanding how to convert marks to SGPA is essential for tracking your academic progress and making informed decisions about your studies. Remember that SGPA is just one measure of academic performance – consistent effort, understanding concepts, and developing practical skills are equally important.
Pro Tip: Keep a semester-wise record of your SGPA to track improvement trends and identify areas needing attention. This will help you make better academic decisions and plan your study strategies effectively.
Whether you’re using an online marks to SGPA calculator or calculating manually, the key is consistency and accuracy in your inputs. With practice, you’ll become proficient at quickly estimating your SGPA and understanding how different grades impact your overall academic performance.
