How it works
- Semester hours = quarter credits × 2/3. Quarter credits = semester hours × 1.5.
- 15 quarter credits → 10 semester hours. 10 semester hours → 15 quarter credits. 90 quarter credits → 60 semester hours.
- 4 quarter credits display as 2.67 semester hours, and 5 as 3.33, rounded to two decimals.
- ECTS uses a separate 2:1 rule of thumb and does not change the quarter conversion.
- Nothing is uploaded. Ask the registrar before you treat a conversion as official.
