Percentage to GPA

Both directions, one editable table — and the honest print-out of how two real schools would read the same score differently.

Entered exactly as graded. No rounding is applied.

The table (editable, both columns)

Each row is a letter, the minimum percent for it, and the grade points it earns. Change any number and the result recomputes. Scores below the lowest minimum earn an F at 0 points.

The default composes this site's common plus-minus bands with the standard 4.0 ladder. It is a convention, not a standard: United States University publishes A at 94 with 3.67-style steps, and North Carolina's statewide high school scale starts the A at 90 with no plus-minus at all — a State Board decision reported in October 2014 and in force since 2015–16. Your school's table wins — edit this one to match it.

Questions

Is there a universal percentage-to-GPA conversion?

No, and any converter that pretends otherwise is choosing a table for you silently. This one shows its table, lets you edit every minimum and every points value, and prints the same score on two real published scales that disagree, so the variation is visible in the result itself.

Which two published scales does the result compare against?

United States University's general catalog table, where an A starts at 94 and carries x.33/x.67 point steps, and the North Carolina State Board of Education's statewide 10-point high school scale, where an A starts at 90, there is no plus-minus, and points run in whole numbers. A 91, for example, is an A- worth 3.67 at USU and an A worth 4.0 on the NC scale.

Why does the GPA-to-percent direction return a range instead of one number?

Because banded tables map every percent in a band to one points value. Reversing that honestly gives you the band back, not a single percent. A 3.7 on the default table means somewhere from 90 to just under 93 - the table cannot say where.

What happens when my GPA falls between two rows, like 3.5?

The tool names the two rows it sits between and refuses to invent a percent. Averages of several courses land between ladder values all the time; single scores cannot, so no percent on the table produces exactly 3.5. Both neighboring bands are the honest answer.

Can I share a result?

The direction and the value you entered are stored in the page URL, and the copy-link button copies it. Edits to the table are not stored in the URL, so a shared link opens with the default table.

Calculator, not counselor: this page does arithmetic on the numbers you give it. For anything that affects standing, scholarships, or graduation, confirm with your school.
