How to use the percentage to letter grade converter
When you have a percentage score but need the letter grade and the grade points behind it, this converter does the mapping. Enter your score and the cutoffs from your syllabus, and it reports the letter from A+ to F, the grade points on the scale you pick, and how many points sit between you and the next grade.
The check runs from the top down and picks the first tier your score reaches or passes. With an A cutoff of 93, a score of exactly 93 is an A. The points needed for the next grade are rounded up, so earning that many really does move you into the higher tier.
Cutoffs differ by school, department and instructor, so nothing here is authoritative. Two common examples are offered and every value stays editable. Curved courses set grades from the class distribution instead of fixed cutoffs, in which case this result is only a rough reference.
Grade points follow the usual mapping for the 4.0, 4.3 and 4.5 scales. Schools that use plus and minus grades throughout, or that weight honors and advanced courses, will publish a different table. The full cutoff table is shown under the results so you can see every tier at once.
