Convert GPA to a 4.0 scale
Use a source maximum that matches the scale printed beside your GPA. The worksheet returns a proportional estimate and keeps the original value in view.
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.
The proportional formula
Divide the reported GPA by the highest possible GPA on that same scale, then multiply by 4.0.
For example, 3.7 on a 5.0 scale becomes 3.7 ÷ 5.0 × 4.0 = 2.96. This answers a scale-conversion question; it does not reproduce an institution's transcript policy.
| Reported value | Source scale | 4.0 estimate |
|---|---|---|
| 3.7 | 5.0 | 2.96 |
| 7.5 | 10.0 | 3.00 |
| 85 | 100 | 3.40 |
Why a 5.0 scale is not always weighted the same way
Some schools add one point for advanced classes, some add half a point, and others weight only selected courses. If 5.0 represents course rigor rather than a simple numeric maximum, enter the actual courses in the weighted-to-unweighted worksheet instead of subtracting one point from an aggregate GPA.
What to submit
If an application asks for the GPA exactly as reported, submit the original value and scale. If it supplies its own conversion instructions, use those instructions. Use this estimate for planning and comparison, not to overwrite an official record.
