Frequently Asked Questions

Last updated: July 9, 2026

Answers to the questions we're asked most often about CGPA-to-percentage conversion.

Is the HEC formula on this site official?
Yes for Pakistan — the calculator's "HEC Official Formula" option reproduces the piecewise conversion table published by Pakistan's Higher Education Commission for the 4.0 and 5.0 CGPA scales. The "Quick Linear (×25)" option is a simplified estimate some students use for quick reference, but it slightly overstates your percentage at the top end compared to the HEC table.
Which formula should I use for job or scholarship applications (FPSC, PPSC, CSS, HEC equivalence)?
Use the HEC Official Formula result, but always cross-check it against the percentage printed on your official transcript. The transcript figure is legally authoritative; this calculator is a reference tool.
Why does India show three different formulas?
India has no single national standard. The General formula (CGPA × 9.5) is the most widely used estimate, but Anna University and VTU (among others) publish their own formulas. Check your consolidated marksheet or ask your controller of examinations which one your institution uses.
Do the US, UK, Australia and Germany results have official formulas?
No. None of these countries have a government-mandated CGPA-to-percentage conversion. The calculator uses commonly accepted linear estimates for the US, Canada, Australia and Germany, and direct classification bands for the UK. Treat these as approximations, not certified figures.
Do you store or see the CGPA I enter?
No. All calculations happen locally in your browser using JavaScript. Nothing is sent to a server, logged, or stored. See our Privacy Policy for details.
Is this calculator affiliated with HEC, AICTE, or any university?
No. This is an independent tool. We reference publicly available formulas for educational purposes but are not affiliated with, endorsed by, or representing any of these organizations. See our Disclaimer.
My university uses a different scale or formula. What should I do?
Use the Universal tab and enter your own maximum possible score for a simple proportional estimate, or contact us with your university's formula so we can consider adding it.
Is this tool free?
Yes, completely free, with no account or sign-up required.
