Percentage to GPA CalculatorFrequently Asked Questions
Letter grade to GPA conversion is the process of translating alphabetical grades (like A, B, C) into a numerical Grade Point Average (GPA) value. This conversion is commonly used in educational institutions to calculate overall academic performance.
On a 4.0 scale, letter grades typically convert as follows: A+ and A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, D- = 0.7, and F = 0.0.
The 4.0 scale is the most common GPA scale in the United States, with A being the highest at 4.0. The 5.0 scale is used in some institutions, particularly for weighted GPAs in high schools where advanced courses may award up to 5.0 for an A grade.
Converting letter grades to GPA is necessary for calculating your overall academic performance, applying to colleges or graduate schools, qualifying for scholarships, or meeting academic requirements for graduation or honors programs.
