GPA Calculator — GPA (Grade Point Average) is the standard way to summarize your academic performance. Each course contributes a number of grade points based on the letter grade (or numeric grade, depending on the scale) multiplied by the number of credit hours. The total is then divided by the total credits to give a single number on your chosen scale.

GPA Calculatorとは？
GPA (Grade Point Average) is the standard way to summarize your academic performance. Each course contributes a number of grade points based on the letter grade (or numeric grade, depending on the scale) multiplied by the number of credit hours. The total is then divided by the total credits to give a single number on your chosen scale.
Add a row per course, set the credit hours and grade, and the calculator keeps a running weighted GPA. Switch the scale on the fly — the same grades will produce a different GPA on the 4.0 vs 5.0 vs percentage scale.
