What this result does not account for
- US ratios are conventions, not standards
- ECTS grades are cohort-relative, not absolute
In short: ECTS measures total workload, not classroom hours: 60 ECTS is one full-time year (30 a semester), each credit carrying 25–30 notional hours — 1,500–1,800 hours a year. The common US bridge is 2:1: 60 ECTS ≈ 30 US semester credits (or 20.000000 quarter credits). A European bachelor's runs 180–240 ECTS; a master's 60–120. Every conversion on this page is a convention, not a treaty — the receiving institution's rule always wins.
Formula
US ≈ ECTS ÷ 2 ··· quarter ≈ ECTS ÷ 3 ··· hours ≈ ECTS × 25–30
ECTS (the European Credit Transfer and Accumulation System) prices everything a course demands — lectures, labs, reading, assessment — while US semester hours price contact time. That mismatch is why the bridge is 2:1, not 1:1. The scale: 60 ECTS a full-time year, 30 a semester; bachelor's degrees run 180–240 ECTS, master's 60–120. One ECTS credit represents 25–30 hours of notional learning, giving 1,500–1,800 hours per year. The US ratio is the widely used 0.5 — many US universities apply exactly that; none is obliged to.
Worked Example
- Read the ECTS total off the transcript.
- Convert to US semester or quarter credits.
- See the notional-hour workload.
- Confirm with the receiving institution.
Defaults: 60 ECTS → 30 US semester credits (or 20.000000 quarter credits), 1,500–1,800 notional hours — a full-time year. A 240-ECTS bachelor's converts to 120 US credits, the classic four-year American degree load; a semester abroad's 30 ECTS is a US-full-time term at 15 credits.

Methodology & Editorial Standards
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.
This engine was reconciled against an independent reference implementation and hand-verified for the worked example above before release. Our full five-stage review process is published on the About Us page.

ECTS Converter — 8 Expert FAQs
8 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
What exactly is one ECTS credit?
A unit of total student workload: 25–30 notional hours covering every course demand — contact time, lab work, reading, papers, exam preparation. Sixty of them per year (1,500–1,800 hours) is the definition of a full-time European student under the Bologna system.
How do ECTS credits convert to US credits?
The common approximation is 2:1 — one ECTS equals half a US semester credit — so 60 ECTS ≈ 30 US credits and a 240-ECTS bachelor's ≈ 120 US credits. There is no official standard; US institutions set their own ratios, and many do use 0.5. Treat any converted number as an estimate until the registrar speaks.
Why isn't the conversion one-to-one?
Because the systems measure different things. ECTS counts total workload including independent study; US credit hours anchor on classroom contact with outside work assumed. A European course with heavy reading and no lecture hall can carry the same ECTS as a US course with triple the seat time.
What are ECTS grades A to E?
A relative scale over the students who PASSED: A is the top 10%, B the next 25% (to 35%), C the next 30% (to 65%), D the next 25% (to 90%), E the lowest 10% of passers. FX and F fail. An ECTS grade is a rank inside a cohort, not a percentage — 'A' means 'top tenth of this cohort', nothing absolute.
How many ECTS is a bachelor's or master's?
Bachelor's: 180–240 ECTS (three to four years of 60). Master's: 60–120 (one to two years). The 60-ECTS year is the fixed drumbeat underneath both, which is why a 'three-year European degree' converts cleanly to the 90 US credits many American graders expect.
What is the ECTS grading table?
Since a 2009 revision, institutions publish a table showing how their local grades map to A–E using two or more years of cohort data — students, percentages, cumulative percentages. Guidance treats tables built on fewer than 30 passing students as statistically unreliable. Ask for it with any transcript that carries ECTS grades.
Do US universities accept ECTS credits?
Most recognize the system and many apply the 0.5 ratio during admission evaluation, but awarding transfer credit is each institution's call, made course by course. Study-abroad students should get a pre-approval in writing: the ECTS amount converts fine, the content mapping is where credits die.
How do quarter-system schools convert ECTS?
The same workload logic: 1 ECTS ≈ 0.33 quarter credits, so 60 ECTS ≈ 20.000000 quarter credits. Quarter terms pack more, shorter terms — a quarter-year runs 45 quarter credits against the semester system's 30 — and the ECTS year maps to both at the same workload.
