Swim Time Converter

Your details

Enter your time as minutes:seconds.hundredths (e.g. 1:02.34) or just seconds.hundredths (e.g. 58.75).
The pool type where the original time was swum.
Stroke affects how much time is gained from turns and underwater phases.
Event distance in meters (SCM / LCM) or yards (SCY). The 1500 m / 1650 yd distance freestyle uses a special conversion factor.

100-Freestyle converted from Short Course Yards (25 yd).

  • Short course pools have more turns per length than long course, so SCY and SCM times are typically faster than LCM for the same swimmer.
  • These conversions are statistical estimates. Individual turn efficiency, underwater distance, and pacing strategy all affect where a swimmer lands relative to the predicted equivalent.

Next stepTo compare across seasons, convert all your personal bests to LCM equivalents - this is the format used for Olympic qualifying standards.
