High School GPA Calculator
🎯 What Is a GPA and Why Does It Matter?
GPA stands for Grade Point Average, a standard way of measuring academic achievement in the U.S. Each letter grade corresponds to a numerical value:
| Grade | GPA Value |
|---|---|
| A | 4.0 |
| B | 3.0 |
| C | 2.0 |
| D | 1.0 |
| F | 0.0 |
GPA is calculated by averaging these values based on the grades you’ve earned. A high GPA can significantly improve your chances of getting into your dream college, securing internships, or qualifying for academic awards.
