You may wish to convert the percentages you have calculated to a letter grade. Alternatively, you may wish to know the percentage of a particular assignment where your teacher provided only the letter grade. The letter grading scale varies greatly depending on where you are going to school, but this is the most commonly used scale in the United States:   A = 93 - 100% A- = 90 - 92% B+ = 87 - 89% B = 83 - 86% B- = 80 - 82% C+ = 77 - 79% C = 73 - 76% C- = 70 - 72% D+ = 67 - 69% D = 63 - 66% D- = 60 - 62% F = 0 - 59%
