Punjab Technical University SGPA to Percentage Formula
Punjab Technical University uses a specific formula to convert SGPA to percentage. The official formula used by PTU is:
This formula is applicable across all faculties and programs at Punjab Technical University. It's widely accepted for various purposes including job applications, higher education admissions, and scholarships.
Example Calculations
Let's understand how to convert Punjab Technical University SGPA to percentage with some examples:
Example 1: Converting SGPA 8.5 to Percentage
Using the formula: Percentage = (SGPA × 10) - 7.5
Percentage = (8.5 × 10) - 7.5
Percentage = 85 - 7.5
Percentage = 77.5%
Result: An SGPA of 8.5 at Punjab Technical University is equivalent to 77.5%.
Example 2: Converting SGPA 7.2 to Percentage
Using the formula: Percentage = (SGPA × 10) - 7.5
Percentage = (7.2 × 10) - 7.5
Percentage = 72 - 7.5
Percentage = 64.5%
Result: An SGPA of 7.2 at Punjab Technical University is equivalent to 64.5%.
Punjab Technical University Grading System
Punjab Technical University follows a 10-point grading system. The complete grading scale used by PTU is as follows:
| Range of Marks | Letter Grade | Grade Points | Result |
|---|---|---|---|
| 90-100 | A+ (Outstanding) | 10 | Pass |
| 80-89 | A (Excellent) | 9 | Pass |
| 70-79 | B+ (Very Good) | 8 | Pass |

| Below 40 | F (Fail) | 0 | Fail |
Note that Punjab Technical University has a passing threshold of 40%, which corresponds to a grade of 'E' and 3 grade points. Any score below 40% results in an 'F' grade, requiring the student to reappear for the examination.
How Punjab Technical University Calculates SGPA
SGPA calculation at Punjab Technical University follows these steps:
- Each course is assigned credit points based on the number of lecture/tutorial/practical hours per week.
- Students are awarded grade points (GP) for each course based on their marks.
- The credit points for each course are calculated by multiplying the grade points obtained by the course credits.
- The SGPA is calculated using the formula:
Example of SGPA Calculation at Punjab Technical University
Here's an example of how Punjab Technical University calculates SGPA for a student in a semester:
| Course | Credits | Marks Obtained | Grade | Grade Point (GP) | Credit × GP |
|---|---|---|---|---|---|
| Engineering Mathematics | 4 | 85 | A | 9 | 36 |
| Computer Science | 4 | 76 | B+ | 8 | 32 |
| Digital Electronics | 3 | 82 | A | 9 | 27 |
| Engineering Mechanics | 4 | 68 | B | 7 | 28 |
| Communication Skills | 2 | 78 | B+ | 8 | 16 |
| Total | 17 | - | - | - | 139 |
SGPA = Total(Credit × GP) / Total Credits
SGPA = 139 / 17 = 8.18
Once you have the SGPA, you can convert it to percentage using the Punjab Technical University formula:
Percentage = (8.18 × 10) - 7.5 = 81.8 - 7.5 = 74.3%
