I'm Abubakar, and I built Grade Average Calculator because I was tired of opening five different tabs just to check a GPA, convert a CGPA, or figure out what I needed on a final exam.
Most calculator sites I found were cluttered with pop-ups, gave no context on how the math actually worked, or buried a simple formula behind pages of unrelated content. I wanted one clean place with tools that just work, and that explain the formula behind every result instead of hiding it.
This site started as a small side project to solve my own problem as a student, and grew into a set of 15 tools covering grades, GPA and CGPA conversions, and a few everyday utility calculators people asked me to add along the way.
