Pracujemy nad kompleksowym przewodnikiem edukacyjnym dla International Grade System Converter. Wróć wkrótce po wyjaśnienia krok po kroku, wzory, przykłady z życia i porady ekspertów.
The International Grade System Converter translates academic grades between the major global standards: US 4.0 GPA scale (letter grades A–F), UK degree classification (First / 2:1 / 2:2 / Third), ECTS European grading (A–F percentile-based), Indian percentage and division (First/Second/Third), German numeric scale (1.0–5.0, where 1.0 is best — inverted from US), Chinese percentage (60% pass), and Australian / Canadian variants. Essential for international students, university admissions, credential evaluators, employers reviewing foreign degrees, and study-abroad coordinators. Each system embeds different assumptions. US GPA is cumulative weighted average where A=4.0, B=3.0, etc., and 'graduate-level' usually requires 3.0+. UK uses honors classification on final-year + dissertation: First (70%+), Upper Second (2:1, 60–69%), Lower Second (2:2, 50–59%), Third (40–49%), Pass (35–39%). ECTS introduced relative ranking (A = top 10%, B = next 25%, C = next 30%, D = next 25%, E = bottom 10%) but most institutions hybridize ECTS with absolute scores. India uses percentage (60%+ First Division, 50–59% Second, 40–49% Third), and many states layer on choice-based credit systems (CBCS) with letter equivalents. The German system trips up nearly everyone: 1.0 is best, 5.0 is failing — the inverse of US/UK direction. A German 1.0–1.5 ≈ US A / 4.0 / UK First. A 2.0–2.5 ≈ B+ / 3.5 / 2:1. A 3.0 is solidly average (US C / 2.0). A 4.0 is the minimum passing grade. Confusing a German 2.0 (good!) with US 2.0 (mediocre C) is a classic credential-evaluator error. WHY conversion matters: international admissions, study-abroad credit transfer, employer credential evaluation, professional licensure (medicine, engineering, accounting cross-border), and visa applications. WES (World Education Services), ECE (Educational Credential Evaluators), and Naric/ENIC services formally evaluate transcripts using these mappings. The calculator gives directional equivalents — final acceptance always depends on the receiving institution's policy.
Mapping table — each system has equivalence bands; normalize to 0–100 percentile, then look up target system band
- 1Step 1 — Select your source grading system from the dropdown
- 2Step 2 — Enter your grade in that system's format (e.g., 3.7 GPA, First Class, 75%, 1.5 German)
- 3Step 3 — Calculator maps the grade to a normalized internal score (0–100 percentile)
- 4Step 4 — Cross-references the score against each target system's equivalence band
- 5Step 5 — Outputs grade in all major systems simultaneously
- 6Step 6 — Highlights notable conversion details (e.g., German inversion, ECTS relative ranking)
- 7Step 7 — Use output for applications, transcripts, or credential discussions
3.7 maps to approximately the 80th percentile — strong but not top-decile.
UK First is the top 10–15% — equivalent to US summa cum laude territory.
Inverted scale — German 2.0 is GOOD, not mediocre like US 2.0
German 1.0–4.0 is passing (1.0 best); US 2.0 is below average. Easy to misread.
Indian First Division (60%+) translates to solid US graduate-school eligibility.

How accurate is the conversion for university admissions?
Directional — final acceptance always depends on the receiving institution's evaluation policy and the specific source institution's reputation. Always submit official transcripts with country-specific context, and let the admissions office do the formal mapping using their established equivalences.
Why is the German scale inverted?
Historical convention — the German system originated from a 'fault count' tradition where lower numbers meant fewer errors, while US/UK scales developed from letter-based excellence ranking where higher means better. Both are internally consistent; the mismatch is purely a translation issue. Austria, Switzerland, Czech Republic, and Slovakia use the same inverted scale.
Is GPA weighted or unweighted in the conversion?
This calculator assumes unweighted 4.0 scale. If your transcript shows 5.0 scale (high schools with weighted AP/IB courses), divide by your school's max to normalize, or use the unweighted GPA. Universities outside the US generally don't recognize 5.0 weighting.
How does ECTS relate to absolute grades?
ECTS was designed as relative (A = top 10%, B = next 25%, etc.) but most European universities hybridize — they assign ECTS letter based on absolute percentage thresholds, not pure ranking. Treat ECTS as a quasi-absolute scale where A ≈ 90%+, B ≈ 80–89%, C ≈ 70–79%, D ≈ 60–69%, E ≈ 50–59%, FX/F = fail.
What about Chinese, Russian, and Japanese systems?
China uses 60% as pass (similar to many Asian systems), 85%+ is excellent. Russia uses 5-point scale where 5 is best (US-direction). Japan uses S/A/B/C/F where S is exceptional, A is excellent. These are partially supported; for formal use, consult WES or ECE evaluations.
Wskazówka Pro
When applying internationally, include both your home-system grade AND a conversion estimate in your application — admissions reviewers appreciate the context even though they'll do their own evaluation. For credential evaluation services (WES, ECE), expect 3–6 weeks turnaround and $150–250 per transcript.
