IIST certifies that the CGPA of all graduates may notionally be converted by Percentage = (CGPA − 0.50) × 10 (CGPA 8.5 → 80%), applicable to all graduates since its inception (2007 onwards). The −0.5 offset means a plain ×10 assumption overstates the percentage by 5 points. (An unreliable online claim of ×9.5 is incorrect.)
