Put your GPA on a 4.0 scale—without hiding the math.
Enter the GPA printed on your record and the maximum value of that scale. The calculator shows a proportional 4.0 estimate, the exact formula, and when a course-by-course calculation is the safer choice.
Calculate the GPA scale conversion
The GPA scale converter maps one reported value from its source maximum to a target maximum with the proportional formula shown below.
Local calculationBoundary: this GPA estimate preserves relative position on the scale. It doesn't reproduce an institution's course, weighting, or credential-evaluation policy.
What this answer means
The result is a mathematical estimate, not a credential evaluation.
A proportional conversion preserves your position on the source scale: current GPA divided by the source maximum, multiplied by 4.0. Schools may instead recalculate individual courses, apply their own grade bands, exclude classes, or ask you to report the original GPA exactly as it appears on your transcript.
| Reported value | Source scale | 4.0 estimate |
|---|---|---|
| 3.7 | 5.0 | 2.96 |
| 7.5 | 10.0 | 3.00 |
| 85 | 100 | 3.40 |
When to use the course worksheet
Use the course-by-course calculator when you have letter grades and credit hours, when a weighted GPA includes honors or advanced-course points, or when the receiving institution publishes a conversion table. It keeps the evidence visible and avoids pretending that every 5.0 or 10.0 system behaves the same way.
A result you can audit
For GPA records, every calculation on this site runs in your browser. No transcript or grade is uploaded. The result panel prints the inputs, formula, rounded estimate and method note so you can compare it with instructions from the institution receiving your application.
The three-label record
A reusable GPA conversion record contains the reported value, its source scale, and the conversion method.
For an 8.2 GPA on a 10-point scale, the record reads 8.2/10, proportional method, 3.28/4 estimate. Keeping those three labels together prevents the converted GPA from being mistaken for an official transcript value.
