It is possible to use short course (25m) times as qualifying times for entry into long course (50m) competitions and vice versa. However, these times first of all need to be converted to take into account the differences in pool lengths, number of turns, etc.
Traditionally this was performed by looking up equivilant times on official ASA tables. However, today this can be done by electronic lookup of those same tables. The current ASA Equivalent Performance Tables were computer generated by SPORTSYSTEMS. This is the official basis for all time conversions used for Championship entries by the ASA and its constituent clubs, counties and regions.
Simply enter the type of conversion, the distance, stroke, and time to be converted below and click submit to obtain the offical conversion time.
