How are academic credits calculated in a degree program at universities abroad?
Credits abroad are calculated from either your study workload or classroom contact hours. The US uses Semester Credit Hours at 120 for a bachelors, Europe uses ECTS at 180 to 240, and the UK uses CATS at 360. One US credit is roughly 2 ECTS or 4 UK credits.
Academic credits abroad measure how much learning a course represents, based either on total study workload or classroom contact hours. Different regions run distinct but comparable systems, so once you understand the logic behind each, converting your progress between them becomes straightforward. Here is how the three major frameworks work.
Major Global Credit Systems
| System | Basis | Full-Time Year | Bachelors Total |
|---|---|---|---|
| USA and Canada (SCH) | Contact hours plus independent study | 30 credits | 120 credits |
| Europe except UK (ECTS) | Total workload hours | 60 ECTS | 180 to 240 ECTS |
| United Kingdom (CATS) | Total workload hours | 120 credits | 360 credits (Honours) |
The Formula and Conversion Ratios
| Item | Detail |
|---|---|
| 1 US Semester Credit Hour | 1 hour of lecture plus 2 hours of study weekly over 15 to 16 weeks |
| 1 ECTS credit | 25 to 30 hours of total study time |
| 1 UK CATS credit | 10 hours of total student workload |
| Standard conversion | 1 US credit is about 2 ECTS, which is about 4 UK credits |
My Advice
When you compare programmes or transfer credits, focus on the annual full-time load rather than a single course number, since 30 SCH, 60 ECTS and 120 CATS all describe the same academic year. To move between systems quickly, multiply US credits by 2 for ECTS, and remember evaluators still expect your original transcript, not your own conversion, as the source of truth.
