GTU Notification No. GTU/Notification/2012/3970 states Percentage Marks = (CPI/CGPA − 0.5) × 10. This page calculates that notified method while retaining its document scope.
For semester results, this calculator uses a credit-weighted average: sum of each semester’s SGPA × its credits, divided by total credits. It does not use a simple average when credits differ.
For the supported conditional method, percentage = (CGPA − 0.5) × 10. The result is rounded to 2 decimal places.

GTU’s Student Support material lists a Percentage Conversion Certificate service. For an official application, use the applicable GTU certificate or the percentage on your academic record rather than this calculation alone.
No. Recruiters, admissions offices, and government authorities set their own eligibility rules and may request an official transcript, percentage certificate, or a specific calculation method. Use their current notice and your academic record.
The displayed percentage method is supported only for the cited ordinance or document. Confirm that your programme and batch use it.
Your marksheet, transcript, certificate, and applicable university instruction take precedence.
