How gpa scale converter works
Grading systems do not share a ruler. A "B" on the US 4.0 scale, 60-69% in the UK, and an ECTS "C" are all conventionally treated as the same achievement, even though the raw numbers look nothing alike. This converter bridges the four systems through one shared 13-step letter ladder: every step of the ladder carries the US percentage band, the 4.0-scale points, the UK honours class and the ECTS grade that are conventionally treated as equivalent.
Enter any one value — a percentage (0-100), a 4.0-scale GPA (0.0-4.0), a UK honours class (First, 2:1, 2:2, Third, Fail) or an ECTS grade (A, B, C, D, E, FX, F) — and the tool finds its rung on the ladder, then reads off the equivalent in all three other systems at once.
Where a value falls between two rungs, the converter says so instead of pretending. An in-between GPA like 3.5 snaps to the nearest step (B+, 3.3) and a note explains the snap; UK classes and ECTS grades map through their representative letter because both are bands, not points. The percentage column always shows a band such as "83-86.9%" — a single number would be false precision across systems with different anchors.
The mapping is the widely used conventional equivalence: First = A-range, 2:1 = B-range, 2:2 = C-range, Third = D-range, Fail = F, with ECTS A/B/C/D/E/F covering the same span from the top down. Universities occasionally use their own transfer tables, so treat the results as a strong default, not an official ruling.
