Convert grades between four international systems: US GPA (0-4.0), ECTS letter grades (A-F), UK degree classification (First/2:1/2:2) and Polish scale (2.0-5.5). Built for Erasmus students and international applicants.
4.0 GPA on the ECTS, UK and Polish grading scales
Convert grades between four international systems: US GPA (0-4.0), ECTS letter grades (A-F), UK degree classification (First/2:1/2:2) and Polish scale (2.0-5.5). Built for Erasmus students and international applicants.
A grade point average of 4.0 does not travel between countries as a number. European admissions read ECTS letters, British universities read degree classes, and Polish universities work on a scale that runs from 2 to 5. The converter above places 4.0 on all three at once and names the band rather than inventing a decimal, because each system groups a range of GPAs into a single grade. That grouping is why two nearby averages can land on the same letter, and why the boundary matters more than the exact figure when you are close to one.

Same student, four different grades - why conversion matters
A Polish 4.5 becomes a 3.7 GPA in the US, an A- on a transcript to Harvard, a B in the ECTS system used across Europe, and an Upper Second (2:1) at a British university. All four numbers describe the same level of performance - but writing the wrong one on an application can cost you an offer. This converter translates between all four systems in one click.
Before and after - what changes when you convert
You write "4.5" on your Erasmus application. The German coordinator reads it as barely passing (German 4.0 = D). Your application lands in the rejection pile.
You write "ECTS B - Very Good" on the same application. The coordinator sees a strong student. Same grade, completely different outcome.

| Polish | US GPA | ECTS | UK Class |
|---|---|---|---|
| 5.0-5.5 | 4.0 (A) | A Excellent | First Class |
| 4.5 | 3.7 (A-) | B Very Good | Upper Second (2:1) |
| 4.0 | 3.3 (B+) | C Good | Lower Second (2:2) |
| 3.5 | 3.0 (B) | D Satisfactory | Third Class |
| 3.0 | 2.7 (B-) | E Sufficient | Ordinary Pass |
| 2.0 | 2.0 (C) | F Fail | Fail |
These mappings follow the European Commission ECTS Users' Guide and the most common US-to-European grade equivalency tables used by credential evaluation services (WES, ECE).
Practical examples
Result: GPA 4.0 (A) - top of the scale, meets most PhD program minimums
Result: ECTS B (Very Good) - well above average for most European programs
Result: Polish 5.0 (Very Good) - recognized as a strong academic record
Result: GPA 3.3 (B+) and UK 2:2 (Lower Second)
Result: GPA 2.7 (B-), ECTS E (Sufficient) - below most scholarship minimums
