Many students often ask, “How to convert obtained marks into CGPA?” Whether you are applying for university admission, scholarships, internships, or jobs, understanding the conversion process between marks, percentage, GPA, and CGPA is essential.
Different universities and countries use different grading systems. Some use percentages, while others use GPA (Grade Point Average) or CGPA (Cumulative Grade Point Average).
In this complete guide, you will learn how to convert obtained marks into CGPA, calculate GPA, convert percentage into CGPA, and understand the most common grading systems used worldwide.
What Is CGPA and How to Convert Obtained Marks into CGPA?
CGPA stands for Cumulative Grade Point Average.
It is a measure of your overall academic performance across all semesters or academic years.
Unlike percentages, CGPA provides a standardized way to evaluate students’ performance.
Example:
- Percentage = 85%
- CGPA = 8.9 (approximately)
Most universities use either:
- 10-point CGPA scale
- 4-point GPA scale
- Percentage grading system
Step 1: Calculate Your Percentage
Before converting marks into CGPA, you need to calculate your percentage.
Formula
[
Percentage = \frac{Obtained\ Marks}{Total\ Marks} \times 100
]
Example
Suppose you scored:
- Obtained Marks = 720
- Total Marks = 800
Calculation:
[
\frac{720}{800} \times 100 = 90%
]
Result:
720/800 = 90%
Step 2: Convert Percentage into CGPA
Many institutions use the following formula:
[
CGPA = \frac{Percentage}{9.5}
]
Example
[
CGPA = \frac{90}{9.5}
]
[
CGPA = 9.47
]
Result:
90% ≈ 9.47 CGPA
