Percentage to letter
Converting a percentage into a letter grade and its GPA points is a constant need for students and teachers. This tool applies a common plus-minus scale in one step.
A score of 88% is a B+ worth 3.3 grade points on the 4.0 scale. Because cutoffs vary between schools, use it as the standard guide and adjust for your institution if needed.
