OGPA to percentage formulas

How does the 10-point formula work?

According to G.M. University's regulations, equivalent percentage of marks = OGPA x 10. An OGPA of 8.2 equals 82%.

How does the 4-point formula work?

Punjab Agricultural University reports OGPA out of 4.00 and first converts it to an Overall Credit Point Average (OCPA) out of 10, then multiplies the OCPA by 10. For undergraduate programmes OCPA = (50 - 10X + 5X²) / 10, and for postgraduate programmes OCPA = (25X - 15) / 10, where X is the OGPA.

So an OGPA of 3.00 equals an OCPA of 6.50 and 65% for an undergraduate, and an OCPA of 6.00 and 60% for a postgraduate.

How is the OGPA itself calculated?

OGPA = sum of (GPA of each semester x credit hours in that semester) / total credit hours in all semesters. A semester with more credit hours carries more weight, so a simple average of your semester GPAs can differ from your OGPA.
