What is GPA Converter?

A GPA converter translates between the three ways a grade gets written down: the percentage on the paper, the letter on the transcript and the grade point used in the GPA formula. The mapping is not a formula but a set of bands, and schools define them slightly differently — the table here is the standard US convention with 90–92% as an A- and 93%+ as an A. The converter also shows the weighted points a course would earn at Honors and AP level, which is the fastest way to see why a 3.7 unweighted can become a 4.2 weighted over a full schedule.

Common Uses for GPA Converter

Turn a percentage grading scale into US letter grades
Understand what a 3.4 GPA means in letter terms
Check the weighted points a course would earn at AP level
Convert international grades into an approximate 4.0 figure

The three notations and when each is used

Percentages appear on graded work and in syllabi; letters appear on transcripts and report cards; grade points appear inside every GPA calculation. Knowing the band boundaries converts between them reliably, and the boundary — 89.5% versus 90% — is often the difference between a B+ and an A- in the GPA.

Converting when the scales disagree

If your school publishes its own band table, treat this converter as a cross-check rather than the authority. The percentage bands are the part most likely to differ: some schools set 93% as the A floor, others 90%. The letter-to-points mapping is much more consistent, and that is the part the GPA formula actually uses.

Frequently Asked Questions

Is there a formula for percentage to GPA?

No exact one — it is a lookup through letter bands, and those bands vary by school. The most common US convention is used here, with 90–92% as A- and 80–82% as B-.

What is a 3.5 GPA in percentage terms?

Roughly 88–90%. A 3.5 sits between a B+ (87–89%) and an A- (90–92%), so a transcript averaging 3.5 is a mix of those two grades.

Can I convert an international grade to a US GPA?

Only approximately. Systems with different band structures — UK honours classifications, Indian 10-point CGPA, German 1–6 — do not map cleanly onto the 4.0 scale. The converter gives a reasonable estimate near the middle of the scale and should not be used as an official equivalency.

Why does the AP column cap at 5.0?

Because 5.0 is the standard weighted ceiling: an A in an AP class is 4.0 + 1.0. Values above 4.0 only appear when a school weights, and the cap stops a perfect record from exceeding what any school reports.
