How to convert UG grades from percentages to GPA?

[the nona]

How to convert UG overall grades from percentages ( e.g 250 marks out of 500 = 50%) to a GPA out of 4 or whatever applicable?I calculated my 70.4% grade to be 2.816~2.82 is this correct?

Thx in advance

Well first of all, for the most part for "official purposes" you need to give them our percentage grade, which you would submit along with your diploma, some also ask for your conversion, but there's no real good systematic way of evaluating this, although it may be good to try and help figure out where you stand. I think a far better indication is a "qualitative one" which figures in how prestigious (or un) your school is, and what your ranking is relative to other students.
