This tool converts a grade point average on the 4.0 scale into its letter grade and the percentage range schools usually associate with it. It’s handy for reading a transcript, comparing GPAs to grade bands, or checking which letter a given average corresponds to.
How it works
The converter uses the standard US unweighted mapping. It takes your GPA (clamped to the 0.0-4.0 range) and returns the highest letter band whose minimum GPA your value reaches. The bands are:
| GPA (min) | Letter | Typical % |
|---|---|---|
| 4.0 | A | 93–100% |
| 3.7 | A− | 90–92% |
| 3.3 | B+ | 87–89% |
| 3.0 | B | 83–86% |
| 2.7 | B− | 80–82% |
| 2.3 | C+ | 77–79% |
| 2.0 | C | 73–76% |
| 1.7 | C− | 70–72% |
| 1.3 | D+ | 67–69% |
| 1.0 | D | 63–66% |
| 0.7 | D− | 60–62% |
| 0.0 | F | Below 60% |
Example
Enter a GPA of 3.5. The tool finds the highest band the value reaches: 3.5 clears the B+ threshold of 3.3 but not the A− threshold of 3.7. So 3.5 maps to B+, typically an 87-89% average.
