This CGPA to Percentage Calculator was built to give students a single place to convert their CGPA into an equivalent percentage — whatever grading system their university uses.
Most calculators online use one generic formula for every country. That's misleading: Pakistan's HEC publishes its own official conversion table, India has at least three formulas in active use, and countries like the US, UK, Australia and Germany don't have a single standard at all. We wanted a tool that is upfront about which formulas are official and which are estimates, instead of presenting everything with false precision.
This tool grew out of a simple frustration: CGPA-to-percentage conversion rules are scattered across university notices, forum posts, and outdated PDFs, and they rarely agree with each other. We built a single place with formula-accurate, transparent conversions so students don't have to guess.
