Convert a letter grade (A, B+, C-, etc.) to its corresponding GPA value using the standard US 4.0 scale.
Letter grades are the most common form of academic assessment in schools and universities worldwide. Whether it's an A, B+, or C-, each letter grade represents a certain level of performance. However, when it comes to GPA (Grade Point Average), those same letters must be converted into numerical values. That’s where our Letter Grade to GPA Conversion tool becomes invaluable.
Whether you're a high school student, college undergraduate, or international applicant trying to understand U.S. grading systems, this tool helps you translate academic scores into GPA quickly, accurately, and intuitively.
GPA stands for Grade Point Average. It is a standardized numerical representation of a student's academic performance over a period of time—typically on a 4.0 scale in the United States. Each course grade you receive (A, B, C, etc.) corresponds to a specific GPA value, and your overall GPA is the average of all these values.
GPA is used in various important academic and professional processes such as:
Here is the most widely used unweighted GPA conversion scale:
| Letter Grade | GPA Value |
|---|---|
| A+ | 4.0 |
| A | 4.0 |

| B | 3.0 |
| B- | 2.7 |
| C+ | 2.3 |
| C | 2.0 |
| C- | 1.7 |
| D+ | 1.3 |
| D | 1.0 |
| F | 0.0 |
There are two types of GPA calculations: unweighted and weighted.
| Letter Grade | Regular | Honors | AP/IB |

| A | 4.0 | 4.5 | 5.0 |
| B | 3.0 | 3.5 | 4.0 |
| C | 2.0 | 2.5 | 3.0 |
| D | 1.0 | 1.5 | 2.0 |
| F | 0.0 | 0.0 | 0.0 |
