The 4.0 GPA scale is the most common grading system used in colleges and universities in the United States. It's a weighted system where letter grades are converted to numerical values, and the average of these values gives your GPA. This calculator helps you determine your GPA based on your course grades and credit hours.
How to Calculate GPA on a 4.0 Scale
The 4.0 GPA scale is calculated by converting each letter grade to its corresponding numerical value, multiplying each value by the number of credit hours for that course, summing these products, and then dividing by the total number of credit hours.
For example, if you have two courses:
- Course 1: 3 credit hours, grade A (4.0)
- Course 2: 4 credit hours, grade B (3.0)
The calculation would be:
This means your GPA would be approximately 3.43 on a 4.0 scale.
