Hello friend,

CGPA is Cumulative Grade Point Average. Although strictly speaking the conversion of CGPA to "percent" is not mathematically correct - since majority of the cases grades are given on relative scores. If CGPA is calculated to the base of 10 [ out of 10 ] them some institutions consider as " Percent = 10 X CGPA". if it is out of 4 we can multiply by 25
