What is a CPI Calculator?

CPI and CGPA measure the same thing at most institutes: a credit-weighted average of your grade points across a semester. Some universities (especially IITs) use the term CPI for the cumulative score across all semesters, while CGPA is used elsewhere — the calculation is identical either way.
Supported use cases: Calculating semester results, converting CPI to percentage for job applications, checking scholarship eligibility, tracking CGPA trends across semesters.
