Time Conversion

Entry times should be related to the course in which the meet is to be conducted, however, it is possible to adjust times between short course and long course using a table of constants.

Constants used must be those that apply to the age group when the time was established, e.g. if the swimmer was 14 years when the time was established, then the 14 years constant would be used even if the swimmer has turned 15 years. This applies to Age & Open events.

NOTE - Australian Open and Age Championship entry times must be achieved in a 50m pool. Converted times will not be accepted.
