Schools use different GPA scales — a standard unweighted 4.0 scale, a weighted 5.0 scale that gives extra credit for honors/AP courses, or other variations entirely. Comparing GPAs across scales (like for a college application) means converting them to a common reference point first.
This calculator rescales an already-known GPA from one scale's maximum to another's, proportionally.
How it works
Enter your current GPA, your current scale's maximum (like 5.0 for a weighted scale), and the target scale's maximum (like 4.0 for the standard scale). The tool scales your GPA proportionally between the two.
- Enter current GPA.
- Enter current scale maximum.
- Enter target scale maximum.

Examples
A weighted 5.0-scale GPA
A 4.3 GPA on a 5.0-point weighted scale converts to about 3.44 on a standard 4.0 scale.
Who should use it
- Getting a rough sense of how your weighted GPA compares to an unweighted 4.0 scale.
- Comparing GPAs reported on different scales from different schools.
Industry applications
- K-12 and higher education admissions
Advantages
- Quick way to get a rough sense of how a GPA compares across scales.
- Works for any pair of scale maximums, not just 4.0/5.0.
Limitations
- A proportional approximation only — doesn't replicate how any specific school actually recalculates GPAs from a transcript.
Common mistakes to avoid
- Treating a proportionally-converted GPA as an official, transcript-verified figure rather than a general approximation.
- Not accounting for the fact that weighted scales already give extra credit for harder courses, which a simple proportional conversion doesn't fully unwind.
Best practices
- Use this as a general estimate for personal reference, but rely on an official transcript evaluation (from a school or college admissions office) for any decision where the exact GPA matters.
Tips
- If you're applying to college, check whether the school recalculates GPA from your transcript directly — many do, which would supersede any self-converted estimate.
