ECTS Grade Converter

About this calculator

The ECTS (European Credit Transfer and Accumulation System) grade converter translates between the European letter-grade scale and the US GPA or UK degree-classification systems. In the legacy ECTS model, grades are assigned by a student's rank within a passing cohort rather than by a fixed percentage score, so the same raw mark can map to different letters depending on the class distribution. Use this tool when applying to European universities, evaluating a transcript from abroad, or explaining your results to an international employer.

How to read your results

In Percentile mode you enter your percentile rank — a conventional rank where higher is better, so 90 means you finished in the top 10 % of the class and 50 is the middle. The headline result is the matching ECTS letter grade (A–E). The coloured distribution strip beneath the result runs from E at the low end (0) to A at the high end (100), highlights the band your rank falls into, and marks your exact position. Two companion stats — the US GPA equivalent and the UK degree classification — appear alongside the grade so you can read all three systems at a glance. In Table mode the result is the grade value converted across systems (ECTS, US letter, UK classification), with the same equivalence stats shown beside it and the full cross-system table for reference.

How it's calculated

For distribution-based conversion the tool applies the legacy ECTS fixed bands, expressed as a conventional percentile rank (higher = better): grade A covers the top 10 % of the passing cohort (percentile 90–100), B the next 25 % (65–90), C the next 30 % (35–65), D the next 25 % (10–35), and E the bottom 10 % (0–10). These fixed bands are the older, widely-used ECTS model; the 2015 ECTS Users' Guide replaced them with institution-specific grade-distribution tables, so they are presented here as the legacy reference. For table-based conversion the tool uses the cross-system equivalence table documented in the Wikipedia article on the ECTS grading scale, mapping each ECTS letter to a US letter grade, a US GPA value, and a UK degree classification. The GPA values used are A = 4.0, B = 3.5, C = 3.0, D = 2.5, E = 2.0, and F / FX = 0.0.

Worked example

A student finishes at the 80th percentile of the passing cohort — better than 80 % of passing students. Enter 80 in the percentile field with Percentile mode selected.

The calculator returns ECTS grade B, US GPA 3.5, and UK classification Upper Second (2:1). The distribution strip highlights the B band (the 65–90 percentile range), confirming the position sits well inside it.

Frequently asked questions

What does the percentile rank mean here?

It is a conventional percentile rank: the percentage of the passing cohort you finished ahead of, where higher is better. A rank of 90 means you beat 90 % of passing students (the top 10 %); 50 is the middle of the class; 5 is near the bottom of the passing group. It is not the same as a percentage score on the exam.

Where do the fixed A–E percentage bands come from?

They come from the older ECTS grading model — the widely-used legacy approach in which grade A always covers the top 10 % of passing students, B the next 25 %, C the next 30 %, D the next 25 %, and E the bottom 10 %, regardless of the absolute scores. Note that the 2015 ECTS Users' Guide moved away from these fixed bands toward institution-specific grade-distribution tables, so treat the fixed bands as the legacy reference model rather than a current prescription.

What do FX and F mean, and how do they differ?

Both FX and F are failing grades. FX ("fail — some more work required") means the student came close to passing and may be allowed to improve the work with limited additional effort. F ("fail — considerable further work required") indicates a more fundamental shortfall. Neither appears in the percentile-based distribution because it covers only the passing cohort.

How reliable are the GPA and UK equivalences shown?

The conversion table follows the mapping compiled on the Wikipedia ECTS grading scale article, which in turn references standard institutional equivalency guides. Individual universities may use their own conversion tables, so treat the equivalences as a widely-accepted starting point rather than a binding rule — always check the admissions office of the institution you are applying to.

Can I convert a UK degree classification or a US letter grade back to ECTS?

Yes. Switch to Table mode, set the From system to UK or US, choose your grade value, and set the To system to ECTS. The reverse mapping is read from the same cross-system table.
