Reverse the rule, not just the number

A percentage does not contain its original grading policy. First identify the university, programme, and regulation year that produced the record. Then reverse that same published formula.

For example, 80% reverses to an estimated 8.00 under VTU 2025 and Anna University R2025, but to 8.50 under JNTUH R25. The arithmetic is simple; choosing the right rule is the important part.

Keep the original percentage visible on applications. Add the estimated CGPA only when the receiving organisation accepts a self-conversion, and name the formula beside it.
