Convert Dutch 1–10 grades to a weighted average, US GPA, and ECTS
Dutch universities grade on a 1 to 10 scale where 5.5 is the pass mark and grades of 9 or 10 are almost never awarded. Because top marks are so rare, a Dutch transcript looks deceptively low to outsiders, and “multiply by 10 for a percentage” misrepresents it. This tool computes your ECTS-credit-weighted average and maps it onto a US 4.0 GPA and ECTS band using standard admissions equivalences.
How it works
Your weighted average across all courses is:
Average = Σ(grade × ECTS credits) / Σ(ECTS credits)
That Dutch average is then mapped onto the US 4.0 scale with bands that reflect strict Dutch marking — for example, an 8.0 (goed, very good) corresponds to about a 3.7–4.0 US GPA, not the 80% a naive scaling would imply. The tool also reports an approximate ECTS grade.
For example, two courses — an 8 worth 15 ECTS and a 6 worth 5 ECTS — give (8×15 + 6×5)/(15+5) = (120 + 30)/20 = 7.5 (ruim voldoende), roughly a 3.3 US GPA.
Tips and notes
- Always weight by ECTS credits, since Dutch programmes mix large theses with small electives.
- 5.5 is the passing line; many institutions round to one decimal, so a 5.45 may round up to a pass.
- A Dutch 9 or 10 is genuinely outstanding and reliably maps to a US 4.0 and a UK First.
- ECTS letter grades officially depend on cohort rank; the band shown here is a numeric approximation.
