GPA to Percentage Converter
Convert a GPA to a percentage — or a percentage back to a GPA — on the standard 4.0 scale.
Conversions use the common US 4.0 scale and are estimates — your school's scale may differ.
GPA to percentage conversion chart
Because letter-grade bands are not evenly spaced, the most reliable way to convert between GPA and percentage is a lookup chart rather than a single formula. Here is the standard 4.0 scale used by many US colleges and the College Board:
| Letter | Percentage | GPA |
|---|---|---|
| A+ | 97–100% | 4.0 |
| A | 93–96% | 4.0 |
| A− | 90–92% | 3.7 |
| B+ | 87–89% | 3.3 |
| B | 83–86% | 3.0 |
| B− | 80–82% | 2.7 |
| C+ | 77–79% | 2.3 |
| C | 73–76% | 2.0 |
| C− | 70–72% | 1.7 |
| D+ | 67–69% | 1.3 |
| D | 65–66% | 1.0 |
| F | Below 65% | 0.0 |
The quick formula (and its limits)
If you just need a rough figure, the common shortcut is percentage = (GPA ÷ 4) × 100. A 3.0 GPA becomes 75%, and a 3.5 becomes 87.5%. It is easy to remember, but it tends to under-report because a 3.0 (a solid B) really corresponds to about 83–86% on the chart, not 75%. Use the formula for a ballpark and the chart when accuracy matters — for example on a college or scholarship application.
Converting percentage to GPA
Going the other way is just as simple: find your percentage in the chart and read across to the GPA. A 91% is a 3.7, an 85% is a 3.0, and a 78% is a 2.3. Switch the converter above to Percentage → GPA to do it automatically. Keep in mind that international scales (for instance the Indian CGPA system or European ECTS grades) use different mappings, so always confirm the scale your institution expects.
Once you know your GPA, the 4.0 GPA scale chart shows every letter grade at a glance, and the high school and cumulative GPA calculators will work out the GPA itself from your grades.
