Pacific Swimming no longer requires that entry times be converted between long course and short course. For meets that require that entry times be proved (such as JOs, Far Westerns, and certain meets in the senior program), meet entry time standards will be provided in both short course and long course, and you may enter a qualifying time achieved in either course.
However, it is important to note that Pacific's Rules and Regulations still specify that when you have achieved a specific class level (for example, B or A) in an event in one course, you are considered to be qualified at that same level in all courses. Accordingly, you must always enter a time which maintains the class for which you've qualified in an event.
For example, if you've achieved a short course A time in an event but have never swum the event or have never achieved at this level in the event long course, you must enter at least a minimum long course A time when you enter the event in a long course meet.
