ECTS credits measure how much study a course or degree involves: one full-time academic year is 60 ECTS, and one credit stands for 25 to 30 hours of work. To convert ECTS to US credits, the most common rule is to divide by 2, so 60 ECTS is about 30 US semester credits. That ratio is a convention rather than a law, and the examples below show US universities turning the same 5 ECTS course into 2, 2.5 or 3 credits.
All figures here come from official or university pages, checked in November 2026.

ECTS stands for European Credit Transfer and Accumulation System. The European Commission describes it as a tool of the European Higher Education Area that helps students move between countries. Its rules are in the ECTS Users' Guide 2015, which education ministers adopted at the Yerevan conference in 2015 as the official guide.
The word that matters is "workload". An ECTS credit counts all the work a typical student needs for a course, including practical work, placements and individual study. US credits are often described by class time: Montana State University, for example, equates a 3-credit course with 3 hours a week over a 15-week semester. Because the two systems count different things, no conversion is exact.
The Users' Guide says a full-time year usually means 1,500 to 1,800 hours of work, so one credit is 25 to 30 hours. Countries and universities pick their own figure inside that range:
So a 6 ECTS course means 150 hours at a 25-hour university and 180 hours at a 30-hour one. The guide itself notes that these are typical figures and that the time an individual student needs will vary.
Under the Users' Guide, a bachelor's degree typically has 180 or 240 ECTS, and a master's typically has 90 or 120, with at least 60 at master's level. Use of ECTS in doctoral programmes varies.
The guide gives 5, 10 and 15 credits as examples of regular course sizes, and half of a 60-credit year is 30. Helsinki sets its bachelor's at 180 credits and its master's at 120. The University of Bologna lists 180 for a first-cycle degree, 120 for a second-cycle degree, and 300 or 360 for single-cycle programmes.

Divide ECTS by 2 for a planning estimate, then check your own university's rule, because it decides the result. Dartmouth's registrar says 1 ECTS is most widely considered equal to 0.5 semester hours, while Temple University notes that different US institutions have different ratios. Five published policies show how far they differ:
Across a 30 ECTS semester, the gap is real. By their published ratios, that semester is 15 credits at Montana State or Washington and Lee and 18 at Temple. A student who assumes the higher figure and then gets the lower one could finish the term 3 credits short.
Rounding can matter more than the ratio. Washington and Lee warns that a 5 ECTS course will often not meet a requirement because it comes back as only 2 credits. If your degree needs a 3-credit course, ask before you enrol whether a 5 or 6 ECTS course will count.
Before you choose a course abroad
Multiply by 2 for a rough figure, so 120 US semester credits is about 240 ECTS. We found no formula that European universities share for this, so treat the result as an estimate and ask the admissions office how it reads a US transcript.
Some publish their working. Utrecht University issues regional credit conversion tables for its exchange partners, including North America. The September 2025 version applies to exchanges in 2026/27, and the Board of Examiners may deviate from it if credits do not match study hours.
Divide UK credits by 2. The University of Warwick says that, in common with other UK universities, it treats 2 of its credits as 1 ECTS:
This is the case where a US-style reading goes wrong. A UK credit is worth half an ECTS credit, and New Mexico Tech values 1 UK-system credit at 0.25 US semester hours against 0.5 for 1 ECTS. The UK Quality Assurance Agency's credit guide for students typically describes one UK credit as 10 notional hours. Two UK credits therefore represent about 20 hours, fewer than the 25 to 30 of an ECTS credit, which shows that the 2:1 rule is an agreed equivalence and not a measure of hours. See the UK grading system guide for how those credits turn into degree classes.
We did not find an official conversion between Indian credits and ECTS, so ask each university how it reads your transcript. Under India's National Credit Framework, which UGC notified on 10 April 2023, one credit means 15 hours of theory, 30 of lab work or 45 of experiential learning in a semester. A year is 1,200 hours and 40 credits.
Two calculations give different answers. These are our arithmetic, not an official rule:
Older degrees may not use this framework, so your own transcript may show different totals. Ask your university for a letter explaining its credit system, and send it with your transcript.

Often yes, but years of study can also count. The University of Mannheim's admission criteria mostly ask for a bachelor's "corresponding to at least 180 ECTS credits or a standard period of study of at least three years". Its Master of Comparative Business Law asks for 240 ECTS or four years. The Users' Guide adds that a comparable bachelor's should be considered for admission whether it has 180 or 240 ECTS, because learning outcomes should be the main factor.
The harder test is often the subject requirement. Mannheim's Master in Data Science asks for courses worth at least 70 ECTS in informatics, mathematics or statistics, its Social Data Science master's asks for 48 in those fields or empirical methods, and its Management master's asks for 36 in business administration. If your transcript does not use ECTS, you may need to convert these course by course. For a German application, see also our guide to masters in Germany.

No. Credits show how much you studied, and grades show how well you did. You earn the credits assigned to a course when you achieve its learning outcomes, and your university reports the grade separately on the Transcript of Records.
The old ECTS grading scale of A to E is, in the Users' Guide's words, "not used anymore". Universities now use a grade distribution table that shows how often each local grade is awarded. A converted GPA therefore needs its own calculation: our guides to what makes a good GPA and the US grading system explain how.
Within an agreed exchange, they should. The Users' Guide says that the home university should fully recognise the credits in a signed Learning Agreement once the Transcript of Records confirms them, without extra exams or work. Moving to a new degree is different, so ask the receiving university which credits it will accept before you rely on them.
Before you apply or leave for an exchange, get the conversion rule in writing from the university that will award your degree. To compare destinations, see the best universities in Europe on EduRank, then use our eligibility check to see which programmes fit your qualifications.
