How the Percentage / Grade Converter Works
This tool converts between percentage scores and letter grades using the standard 13-point US scale (A+ through F, with plus/minus bands). Enter a percentage to see its letter grade, or pick a letter grade to see the midpoint percentage of its range.
Because a letter grade covers a range rather than one exact number, converting letter-to-percentage returns the midpoint of that band, not a guaranteed exact score.
Frequently Asked Questions
What grading scale does this use?
The standard US scale where A+/A is 93–100%, A- is 90–92%, and so on down through F at 59% and below.
Why does letter-to-percentage give just one number?
A letter grade represents a range of percentages, so we show the midpoint of that range as a representative estimate — your actual score could be anywhere within the band shown.
Will this match my school's exact grading scale?
It should be close, but some schools use slightly different cutoffs. Always confirm against your syllabus or institution's official scale for anything that counts.
