Background

When entering a swimming gala with specific qualifying times, a swimmer must normally present times taken from a particular size pool e.g. 25m pool times or 50m pool times. Many swimmers may have swum the required distance and have a satisfactory time, but the time was taken in the wrong size pool. That's where conversion tables come in.

Conversion tables take into account that a swimmer can normally swim a certain distance in a smaller pool faster than in a larger pool. For example, a 200m swim in a 50m pool includes three turns, whereas in a 25m pool there are seven turning opportunities. Since a turn incorporates a push from the wall, seven pushes instead of three usually affect the duration of a swim by a few seconds.
