The short answer
An unweighted GPA uses the same base grade points for every course. A weighted GPA adds a bonus for recognised advanced courses such as Honors, AP or IB. The exact bonus and maximum scale are set by the school.

What changes the calculation
Because schools weight courses differently, a 4.3 or 4.5 weighted GPA cannot be interpreted without its profile. Report both weighted and unweighted results and keep the selected bonus values visible.
