How do you convert CGPA to a percentage?


Wiki User

For students under the 4-point credit system, the procedure is CGPA*18+30=Equivalent percentage

Eg: If CGPA is 3.00, then the equivalent percentage = 3.00*18+30=74%

For students under the 10-point grading system, the procedure is CGPA*9.3=Equivalent percentage

Eg: If CGPA is 9.00, then the equivalent percentage = 9.00*9.3=83.7%


To convert his or her CGPA every one should see his institution marks equivalence certificate.I want to provide a example of RUET university,Bangladesh(visit site: http:/

the conversion formula according to academic council of this university is,

a)percentage marks=79+84(x-3.75); if CGPA , x is between, 3.75<=x<=4.00

b)percentage marks=44+20(x-2.00); if CGPA , x is between, 2.20<=x<=3.75

note: in this university honors marks is 3.75 out of 4.00 scale

first class is 3.00 out of 4.00 scale

and second class is 2.20 out of 4.00 scale


Let one's CGPA is 3.32 out of 4.00 scale,so formula, b will be provided

so,percentage(%)=44+20(3.32-2.00)=70.40% easy.

so I want to add that all universities formula for its conversation is not same.
