Overview of Grade Point Average (GPA)
A Grade Point Average (GPA) is a numerical summary of a student’s average performance in studies over a specific period, usually a semester. GPAs are calculated to two decimals and serve as indicators of academic performance, helping to rank and evaluate students.
In this section, we are going to discuss the Calculation part, conversion of GPA to Percentage, Intro of CGPA and SGPA.
Definition
GPA stands for “grade point average” and is a standardized measure of academic achievement in the U.S. It is typically on a scale of 0 to 4. If your country uses a different grading system, you may need to convert it to calculate your GPA.
How to Calculate GPA
To calculate your GPA, divide the total grade points earned by the total assessed teaching units. Use a scoring system like A=4, B=3, C=2, D=1. Some universities include A+ or A- with adjusted scores like A+ = 4.3, A=4, A- = 3.7, and so on.
GPA’s are of two types:
- Simple Average: A simple average GPA is calculated by adding scores from all courses throughout semesters and dividing by the number of courses.
| Grade | GPA |
| A | 4.0 |
| B | 3.0 |
| C | 2.0 |
| D | 1.0 |
| F | 0.0 |
- Weighted Average: Weighted average is a calculation that considers the varying degrees of importance of the numbers in a data set.
| Grade | Credits | GPA |
| A | 3 | 4.0 |
| A | 3 | 4.0 |
| B | 4 | 3.0 |
| B | 4 | 3.0 |
Definition of Percentage
It indicates a portion of an item in relation to 100 units of that item. “Per cent” literally means “Per hundred”. The grading system indicates the candidate’s academic scores as a fraction of 100.
How to Calculate Percentage
To calculate the percentage, you divide the total marks obtained by the highest possible marks and then multiply by 100.
Example: (15/25) x 100 = 60%
Usually, grade A is taken to be 100-90%, B is 89-80%, C is 79-70% and so on.
If you have complex lettered grades that involve pluses and minuses, the following table can be of use:
| LETTER GRADE | PERCENT GRADE % |
| A+ | 97-100 |
| A | 93-96 |
| A- | 90-92 |
| B+ | 87-89 |
| B | 83-86 |
| B- | 80-82 |
| C+ | 77-79 |
| C | 73-76 |
| C- | 70-72 |
| D+ | 67-69 |
| D | 65-66 |
| E | 65-55 |
| F | Below 55 |
Conversion of GPA to Percentage and Vice Versa
- The Percentage from a simple 4.0 scale
Formula: GPA = (percentage/100) x 4
GPA = percentage divided by 25
If your GPA is 3.0 on 4 then,
Percentage would be 3 x 25 = 75%
- The Percentage from a simple 10-point scale
Formula: GPA = (percentage/100) x 10
GPA = percentage divided by 10
If your GPA is 6.5 on 10 then,
Percentage would be = 10 x 6.5 = 65%
Conversion of Percentage to GPA
- On 4-Point Scale
The grade point average calculation formula on a 4-point scale is given below.
- Divide your percentage by 100.
- Multiply the value obtained by 4.
- The result will be your GPA.
Example:
If you scored 70%, your GPA can be calculated the following way.
70/100 = 0.7
0.7*4 = 2.8
Hence, your GPA is 2.8.
- On 10-Point Scale
As per the 10-point scale grading system, the percentage to GPA conversion is very simple. You just have to divide your percentage by 9.5.
GPA = Percentage/9.5
Example:
Suppose your percentage is 85%. Then your GPA can be calculated the following way.
GPA = 85/9.5
GPA = 8.9

How do I calculate weighted average?
Multiplying each data point by its weight and summing those products. Then sum the weights for all data points. Finally, divide the weight*value products by the sum of the weights.
What is the difference between average and weighted average?
The average is the sum of all values divided by the number of values. In contrast, the Weighted Average is value multiplied by the weight, and added to find a solution.
