How to convert a 5-point scale to a 4-point scale
Some universities grade on a 5-point scale, and applications often expect a 4-point GPA. When both scales run the same direction (higher is better) and are roughly linear, a proportional conversion is reasonable as an estimate.
The proportional method
For two same-direction point scales, multiply by the ratio of the maxima: GPA(4) = value × 4 ÷ 5. So a 4.0 on a 5.0 scale is about 3.2 on a 4.0 scale. Our scale converter does exactly this — select 5.0 as the from-scale and 4.0 as the to-scale.
When the simple method is fine
- Both scales are point-based and run the same way (higher = better).
- You need an estimate for your own planning, not an official figure.
When it is not enough
If grade boundaries differ in shape (one scale is generous at the top, the other strict), a flat ratio distorts the result. For admissions, a credential evaluator converts grade by grade rather than rescaling a single number — so an official equivalency may differ from the proportional estimate.
For Indian 10-point CGPA
Note that converting a 10-point CGPA to a 4.0 GPA is not a simple ratio — use the credit-weighted CGPA to US GPA tool instead, which reflects how evaluators actually map the grades.
The same-direction, similar-shape test
Before trusting the ×4÷5 proportional method, check two things: both scales run the same way (higher = better), and neither is far more generous at the top than the other. If a 5-point scale clusters most students near 4.5 while a 4.0 scale spreads them out, the flat ratio compresses your standing. When the shapes differ, expect an official grade-by-grade evaluation to land somewhat differently from the proportional estimate.
Key takeaways
- Same-direction point scales: GPA(4) = value × 4 ÷ 5 (so 4.0/5 ≈ 3.2/4).
- The scale converter does this; it's an estimate, not an official figure.
- Differing grade-distribution shapes make the flat ratio less reliable.
- A 10-point CGPA is not a simple ratio — use the WES-method tool.
