FAQ
What formula does this GPA to percentage converter use?
It uses a proportional conversion: percentage = (GPA ÷ max scale) × 100.
Is GPA to percentage the same for every university?
No. Many schools use their own mapping tables; this tool is for a simple linear conversion.
Can I convert percentage back to GPA?
Yes—switch to Percentage → GPA and the tool computes GPA = (percentage ÷ 100) × max scale.
What if my GPA scale is not 4.0, 4.3, 5.0, or 10.0?
Select Custom and enter your maximum GPA value.
How should I round the result?
Use the Decimals field to match what your form or report requires (commonly 1–2 decimals).
Why does my converted percentage differ from my transcript?
Your institution may use non-linear grade boundaries, credit weighting rules, or a fixed conversion chart.
Does the tool support comma decimals (e.g., 3,5)?
Yes. Inputs like 3,5 are treated as 3.5.
