Credit Hours to ECTS Converter
Convert US semester credit hours to ECTS credits — or ECTS back to credit hours — for study abroad, Erasmus+, and international applications. Supports three conversion methods including the standard 1:2 ratio, a contact-hours workload model, and custom institutional ratios.
Standard Ratio
1 US credit hour ≈ 2 ECTS
Workload Standard
1 ECTS = 25–30 work hours
Full-Time Semester
30 ECTS = 1 European semester
Typical conversion: 1 US credit hour ≈ 2 ECTS. Most common for North American transcripts.
Who Should Use This Converter
Useful for any student, advisor, or institution working across US and European credit systems.
Study Abroad Students
Understand how your home credits translate to ECTS at a European partner university before you enrol.
Erasmus+ Applicants
Prepare your Learning Agreement with accurate ECTS estimates when official tables are not yet available.
International Admissions
Evaluate incoming transcripts from US, Canadian, or Australian institutions in ECTS terms quickly.
Graduate School Applicants
Convert your bachelor's credit total to ECTS for European Master's programme entry requirements.
Academic Advisors
Provide students with quick estimates when official conversion tables are unavailable or delayed.
Credit Transfer Officers
Audit prior learning records and produce ECTS-equivalent figures for institutional recognition decisions.
How the Three Methods Work
The simplest method. Multiplies your credit hours by a fixed ratio. The widely cited ratio for US semester credits is 1:2, reflecting the typical workload difference between the two systems.
Example: 15 semester credit hours × 2.0 = 30 ECTS (one full European semester).
Builds up from weekly teaching hours. Use this when you know contact hours but not credit hours, or when your institution's ratio differs from 1:2.
Example: 3 contact h/week × 14 weeks × 3 multiplier = 126 hours ÷ 25 = 5 ECTS.
Use when your registrar or partner university specifies an exact ratio. Common institutional ratios include 1:1.5, 1:2, and 1:3.
This method always takes precedence over calculated estimates when an official ratio is available.

| 30 cr | 60 ECTS |
| 120 cr | 240 ECTS |
Common Mistakes to Avoid
Instead: Always check with your registrar. Some programmes use 1:1.5 or 1:3.
Instead: Quarter credits are roughly 0.67× a semester credit. Convert to semester credits first.
Instead: Credits measure workload; grades (A–F) measure performance. They are separate values.
Instead: Host institutions require an official Learning Agreement — not a calculator printout.
Instead: The multiplier (usually 2–3×) accounts for time spent studying outside the classroom.
