GPA to Percentage Conversion — US 4.0 Scale
Updated 2026-04-29
GPA (Grade Point Average) and percentage grades both measure academic performance, but on different scales. This guide explains how to convert between them using the standard US 4.0 scale.
The Standard US 4.0 Scale with Plus/Minus
Most US colleges use this mapping:
| Percentage Range | Letter Grade | GPA Points |
|---|---|---|
| 93–100% | A | 4.0 |
| 90–92% | A− | 3.7 |
| 87–89% | B+ | 3.3 |
| 83–86% | B | 3.0 |
| 80–82% | B− | 2.7 |
| 77–79% | C+ | 2.3 |
| 73–76% | C | 2.0 |
| 70–72% | C− | 1.7 |
| 67–69% | D+ | 1.3 |
| 63–66% | D | 1.0 |
| 60–62% | D− | 0.7 |
| Below 60% | F | 0.0 |
Common Questions
What percentage is a 3.0 GPA?
A 3.0 GPA corresponds to a B, which typically falls in the 83–86% range.
What GPA is 85%?
85% is in the B range (83–86%), which maps to a 3.0 GPA on the standard 4.0 scale.
What percentage is a 3.5 GPA?
A 3.5 GPA sits between B+ (3.3) and A− (3.7). The corresponding percentage range is roughly 87–89% (B+) to 90–92% (A−).
Important Caveat: Institutional Variation
These cut-offs are the most common US college standards, but they are not universal. Individual institutions, departments, and even courses can use different boundaries. Always check your school's official grading scale — your registrar's office or course syllabus will have the definitive table.
Converting a Cumulative GPA to Percentage
To estimate the percentage equivalent of a cumulative GPA, find the row in the table where your GPA falls and use the midpoint of that percentage range. For example, a 3.2 GPA is between B (3.0) and B+ (3.3), so you're likely in the 84–88% range.
