What is CGPA and How Does a CGPA to Percentage Converter Work?
In the Indian education system, the Cumulative Grade Point Average, or CGPA, is widely used as a grading metric. CGPA represents a student's overall academic performance through a numerical scale, typically ranging from 1 to 10 or 4 to 10. It essentially serves as a summary of a student’s academic achievements, much like a report card but in a more standardized form.
The process of calculating CGPA is straightforward when broken down:
Grading by Subject: Each subject is assigned a grade point based on the marks obtained. For example, on a 10-point scale, an A+ could correspond to a 10, an A to 9, and so forth. The exact values can vary between institutions.

Credit Points: Each subject is allotted a certain number of credits, reflecting the time invested or the subject’s importance. Think of credits as a measure of each subject's weight in your overall education.
Calculating Weighted Grades: To determine the weighted grade points, multiply the grade points for each subject by the corresponding credit points.
Summing Up: Add up all the weighted grade points for the term or academic year.
Final Calculation: Finally, divide the total weighted grade points by the total number of credit points earned across all subjects during the period. The result is your CGPA.
Example of CGPA Calculation
Suppose you received grades of 8, 9, 7, 10, and 9 across five subjects, each with equal credit points (assuming 1 credit per subject for simplicity). Multiply each grade by the credits (1 in this case), sum them up to get 43, and divide by the total credits (5). The resulting CGPA is 8.6.
Converting CGPA to Percentage
The method to convert CGPA to percentage can vary depending on the institution, but it generally involves multiplying the CGPA by a specific factor determined by the grading system in use. Typically, converting CGPA to a percentage is quite simple, especially with a CGPA to Percentage Converter. Here’s how you can do it:
- Enter your CGPA into the calculator, ensuring you select the correct grading system beforehand.
- Click on the "Calculate" button.
- The corresponding percentage will be displayed, often accompanied by a pie chart for a visual representation.
Curious about the math behind this? For a 10-point grading scale, the formula is straightforward: CGPA × 9.5 = Percentage.
For example, if your CGPA is 8.2, multiplying 8.2 by 9.5 gives you 77.9%. Thus, a CGPA of 8.2 translates to 77.9%.

Understanding the Difference Between GPA and CGPA
It’s crucial to understand the distinction between GPA (Grade Point Average) and CGPA (Cumulative Grade Point Average) as both terms are frequently used in academic settings:
GPA: Reflects the average performance in a specific term or semester. CGPA: Represents the cumulative average of grades over the entire academic program.
Understanding these concepts and knowing how to convert them to percentages can be immensely helpful in tracking academic performance and meeting the requirements of educational institutions.
