Semester hours
Semester-calendar colleges award semester credit. Oregon State puts a bachelor's at a semester school at usually 120 semester hours.
NCCRS lists every UPI Study course in semester hours

Multiply by 1.5: one semester hour equals 1.5 quarter hours at the University of Washington, Oregon State and the University of Denver, and UW Bothell converts the other way by multiplying quarter credits by two-thirds. UPI Study's credit recommendations are all in semester hours, so at that rate a 3-credit course comes to 4.5 quarter hours and a 4-credit course, such as Calculus 1, to 6. Your college applies its own rule, so check its registrar's page.

The University of Washington and Oregon State award quarter credits; Oregon State puts the same bachelor's at 180 quarter credits.
1 semester hour = 1.5 quarter hours




| Semester hours | Quarter hours | |
|---|---|---|
| Chemistry Lab, Physics Lab | 1 | 1.5 |
| Anatomy and Physiology I and 2 Labs | 2 | 3 |
| Most courses, such as Intro to Psychology | 3 | 4.5 |
| Calculus 1, 2 and 3, Discrete Mathematics | 4 | 6 |
| A bachelor's degree (Oregon State) | 120 | 180 |
| Junior standing at UCLA | 60 | 90 |
The University of Washington's own words: "To convert semester to quarter credits, multiply by 1.5." The University of Denver adds that other formulas apply when a college follows neither a standard quarter nor a semester calendar. Every UPI Study course is self-paced and online.


4.5, at the 1.5 rate the University of Washington, Oregon State and the University of Denver publish. Oregon State says it plainly: “A 3 semester credit class is equivalent to 4.5 quarter credits.” Most UPI Study courses carry an NCCRS recommendation for 3 semester hours.
Multiply by two-thirds. UW Bothell, a quarter-system campus: “To convert quarter credits to semester credits, multiply by two-thirds.” So 45 quarter credits make 30 semester credits. The University of Denver notes that other formulas apply when a college follows neither a standard quarter nor a semester calendar.
Semester hours. NCCRS lists every UPI Study recommendation in semester hours: 1 for Chemistry Lab and Physics Lab, 2 for each Anatomy and Physiology Lab, 3 for most courses and 4 for Calculus 1, 2 and 3 and Discrete Mathematics. A quarter-system college turns them into its own quarter credits.
No. Oregon State puts a bachelor's at a semester school at usually 120 semester hours against 180 quarter credits on the quarter system: “So you are doing the same amount of work – it is just divided up in a different way.”
Calculus 1 (Math 165) carries an NCCRS recommendation for 4 semester hours, which is 6 quarter hours at the 1.5 rate. Calculus 2, Calculus 3 and Discrete Mathematics carry 4 semester hours too.
Yes, at the same rate. Chemistry Lab and Physics Lab carry 1 semester hour each (1.5 quarter hours), and each Anatomy and Physiology Lab carries 2 (3 quarter hours). Each is a set of virtual labs done online; see lab vs non-lab science credit for what counts as a lab.
It depends on the college. UCLA lists junior-level standing for transfer applicants as 60 semester or 90 quarter units completed, and UW Bothell counts a junior from 90 to 134 quarter credits.
