How the Percentage to GPA Calculator (4.0 Scale) works
The College Board publishes a typical conversion: A and A+ (93% and up) are 4.0, A− (90 to 92) 3.7, B+ (87 to 89) 3.3, B (83 to 86) 3.0, and so on down to D (65 to 66) at 1.0 and E/F below 65 at 0.
Schools differ: some put the A cut-off at 90 with no plus/minus grades, and weighted GPAs give honors and AP courses extra points. Check your school’s scale.
