Applying to U.S. universities require you to declare your GPA. But if the transcript of records have grades in percentage, students try to make a percentage to GPA conversion.
- Percentage Scale: 0 to 100. (e.g., 75%, 88%)
- GPA Scale: 0 to 4.0 in USA (like GPA of 3.67)
I was in the same situation a few years back, so I tried searching for different ways to use a GPA calculator for converting my academic percentage of 80% to GPA.
So the common question here is, "Is there a universal formula to convert percentage to GPA".
Percentage to GPA conversion
You might be looking for some tables that will map your percentage score into GPA like this one:
|81 to 100||4.0|
|61 to 80||3.50|
|51 to 60||3.00|
|41 to 50||2.50|
If you do, I can very well say that you are making a huge mistake.
If you want to know why the above table will not work, you need to first understand what is GPA and how GPA is calculated.
Still, many students even after reading this article continue to ask the question, "How to calculate GPA from their academic score?"
So I do hope you will read the article at least so that you don’t need to you ask the same question.
Grade Point Average (GPA)
The Percentage Score (1 to 100) system is used in various countries such as India. But in the U.S., schools use the GPA system for grading students.
GPA Vs Percentage
Both GPA and % assign grades to students, but they are essentially calculated in different ways. They are not the same and it’s not possible to equate or compare the two.
How is GPA Calculated
Grades will be assigned to a student for each course (A = 4.0; B = 3.0; C = 2.0 ; D = 1.0; F = 0).
And each course has credit hours. Usually, graduate level courses will have 3 credit hours per course.
Lets’ say at end of the semester, a professor gives the grade of B to the course database, Grade A to course networks and Grade A to the course software testing. The GPA will then be calculated as follows:
- Total Grades = Sum of (Grade * Credit Hours)= B*3 + A*3 + A*3 = 3*3+4*3+4*3 =33
- Total Credit Hours = 3+3+3 = 9
- GPA = Total Grades/Total Credit Hours = 33/9 = 3.66
U.S. universities will have some some form of evaluation to convert percentage grades into GPA and that varies with each university. Each school has its own GPA calculator.
So basically you really can’t convert academic percentage or CPGA into GPA. So the only sound action is to just use and write your actual grade, i.e., if in percentage, in a college admission application.
U.S. colleges will know what to do with your percentage score. You can write like 79/100 or 79%. That is more than enough.
