How is GPA converted to percentage?

On a 4.0 scale, percentage = (GPA ÷ 4.0) × 100. On a 10-point scale, percentage = (GPA ÷ 10) × 100 or your institution's published multiplier. Always check your transcript or registrar for the official formula — conversions between scales are approximate mappings, not universal rules.

Can I convert percentage back to GPA?

Yes. Switch to Percentage → GPA and enter your percentage. The calculator reverses the selected scale formula so you can move between systems when applying to schools or employers that report grades differently. Verify the output against your institution's official conversion table.

Which grading scales are supported?

Common 4.0, 5.0, and 10-point scales are supported with transparent formulas shown on the page. Institution-specific rules, plus/minus grades, and weighted honors GPA may differ — use this tool for planning and always confirm with your school's published conversion policy.
