Formula Used
Percentage from GPA = (Input GPA / Scale Maximum) × 100
4.0 GPA Equivalent = (Percentage / 100) × 4
5.0 GPA Equivalent = (Percentage / 100) × 5
10.0 GPA Equivalent = (Percentage / 100) × 10
Quality Points = 4.0 GPA Equivalent × Credit Hours
Letter Grade Mapping uses defined percentage bands. Letter inputs convert through the midpoint of each band for consistent equivalence.
