The bands are 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 and F below 60. These are common reference bands, not a rule for every school.
| Minimum percentage | Letter grade | GPA points |
|---|---|---|

| 87 | B+ | 3.33 |
| 80 | B− | 2.67 |
| 60 | D− | 0.67 |
Number to letter grade converter: Letter grades are categories
For GPA records, a grade-band conversion is stepped: 89% and 87% can both be B+, while 90% changes to A−. That is different from a proportional converter, which changes continuously with every point.
Number to letter grade converter: Check plus/minus treatment
For GPA records, some institutions omit plus and minus grades, cap A+ at 4.0, or assign A+ 4.33. Select the table published by the organization making the decision. The final GPA note retains this method context.
