GPA Scale Converter
Convert any one of GPA, percentage or letter grade into the other two.
Why the same GPA can mean different percentages
GPA scales, percentage grades and letter grades aren't perfectly interchangeable — a 4.0-scale GPA groups a whole range of percentages (say 93 to 100) into a single number, so converting from GPA back to percentage can only give you a typical range, not one exact figure. Converting from a percentage or a letter grade to GPA is more precise, since those map onto a specific grade band using a standard breakpoint table (93–96.99% = A = 4.0, 90–92.99% = A− = 3.7, and so on).
Converting foreign or unfamiliar grades to a US GPA
This tool is also genuinely useful if you're applying to a US school with grades from a different system — a percentage-based report card, a different country's scale, or letter grades that don't map 1-to-1 onto the American A–F system. Converting your percentage or nearest-equivalent letter grade here gives a reasonable estimate of the US 4.0 equivalent, though many universities and credential-evaluation services (like WES) use their own official conversion tables, so treat this as a starting point for planning, not a substitute for an official evaluation.
Frequently asked questions
Which conversion table does this use?
A standard, widely used US breakpoint table: 97–100% is A+, 93–96.99% is A, 90–92.99% is A−, down through the B, C and D bands to F below 60%. Individual schools sometimes use slightly different cutoffs, so check your syllabus or catalog if you need an exact match.
Why is the percentage shown a range instead of one number?
Because many different percentages map to the same GPA and letter grade — a 93% and a 96% are both a 4.0/A under this table. The range shown is that grade band, with the midpoint given as a single representative estimate.
Can I use this to convert international grades?
As a rough estimate, yes: convert your percentage (or your best-guess US-letter equivalent) using this tool to get a ballpark 4.0 GPA. For anything official — a college application, transfer credit, a visa or scholarship — use your target school's own conversion policy or a recognized credential evaluation service instead.
Does a plus or minus always change the GPA?
Under this scale, yes, by 0.3 or 0.33 typically (A vs A− vs B+, for example). Some schools don't use plus/minus grades at all, or don't apply them at the GPA level — check whether your school's scale actually distinguishes them before relying on the exact decimal.
