How many ECTS equal one US credit hour?

The common range is 1.5 to 2 ECTS per US semester credit hour. Many US institutions use 2 ECTS = 1 US credit, while some use 1.5, so always confirm with the receiving institution.

Why is the ratio a range and not exact?

ECTS measures total student workload (about 25-30 hours each), while US credits measure contact hours plus expected study. The systems are structurally different, so institutions adopt slightly different ratios.

How many US credits is a full European year?

A full academic year is 60 ECTS. At 2 ECTS per US credit that equals 30 US credits, which matches a typical full US academic year of two 15-credit semesters.

Which ratio should I use for credit transfer?

Use the ratio your receiving university publishes. This tool lets you try 1.5, 1.75, and 2 so you can see the range, but the official figure is set by the institution awarding the credit.

Does this work for both directions?

Yes. Select ECTS-to-US or US-to-ECTS and the converter applies the chosen ratio in the correct direction with rounding to one decimal place.

What is the ECTS Credit Hour Converter?

Convert ECTS credits to US semester credit hours or the reverse using the standard ratio where 1 US credit equals roughly 1.5-2 ECTS, helping students transfer credits between European and American university systems. It runs free in your browser on Gera Tools, with nothing uploaded.

Convert between ECTS and US credit hours

The European Credit Transfer System (ECTS) and the US semester credit hour measure study differently, so transferring credits between them needs a conversion ratio. A full academic year is 60 ECTS or about 30 US credits, giving a working ratio of roughly 2 ECTS per US credit, though some institutions use 1.5. This converter applies your chosen ratio in either direction.

Why the two systems differ

An ECTS credit represents roughly 25–30 hours of total student workload — lectures plus private study, assignments, and exam preparation. A US semester credit hour, by contrast, is anchored in contact time: one hour of lecture per week over a 15-week semester, plus expected reading time. Because the ECTS definition is workload-based and the US definition is contact-time-based, the systems are structurally different, which is why no single exact conversion ratio exists.

The practical consequence is that US graduate schools and professional programs each set their own conversion policy. Common institutional choices:

Ratio (ECTS per US credit)	Who uses it
1.5	Some US graduate schools, especially for science/engineering programs
1.75	A middle-ground estimate used by some transfer offices
2.0	The most common ratio; matches the 60-ECTS-year to 30-US-credit-year symmetry

How it works

The conversion is a single multiplication or division by the chosen ratio R (ECTS per US credit):

US credits = ECTS / R
ECTS       = US credits × R

With R = 2, 60 ECTS becomes 60 / 2 = 30 US credits, and 30 US credits becomes 30 × 2 = 60 ECTS. The tool rounds results to one decimal place and lets you compare all three ratios side by side.

Worked examples

Example 1 — incoming exchange student: A student from Germany completed a semester at a partner university and earned 30 ECTS. Their home US university uses R = 2, so the transfer office will award 30 / 2 = 15 US credits — the equivalent of a standard full-time semester load. Under R = 1.5 the same 30 ECTS would yield 20 US credits.

Example 2 — US student going abroad: A US student with 12 US credit hours of approved exchange courses needs to know the ECTS equivalent for their host institution’s learning agreement. At R = 2, that is 12 × 2 = 24 ECTS — a reasonable semester load in most European systems where 30 ECTS is full-time.

Common mistakes to avoid

Using the wrong direction. Dividing when you should multiply (or vice versa) doubles your error. The tool enforces the correct direction when you set the conversion mode.
Assuming the ratio. Never assume your institution uses R = 2. Contact the registrar or check the published credit-transfer policy, especially for graduate admissions.
Treating the result as final. This tool produces a planning estimate. Official credit evaluation requires institutional review of syllabi, grades, and course-level equivalency — a number alone is not a transfer decision.
