About this tool
Letter grade conversion maps a percentage (or points out of max) to a US-style letter and 4.0 points, or estimates a 10-point mark. Bands such as A = 93–100 are common defaults you can treat as approximate.
Schools disagree on plus/minus cut points and rounding. Use your syllabus whenever it conflicts with the default table.
Percent-to-GPA and ECTS tools cover other mapping problems beyond a single letter.
