Swim Pace Calculator
Swimmers measure effort as time per 100 metres, not minutes per kilometre. Enter the distance you swam and how long it took, and this calculator gives your pace per 100 m and per 50 m, plus your speed in metres per second and kilometres per hour. Use it to set interval targets, pace a distance swim, or compare pool sessions and open-water times on the same scale.
Pace per 100 m is the standard way swimmers compare efforts. A typical lap-fitness pace is around 2:00/100 m; competitive freestyle is well under 1:30/100 m. Times here assume a constant pace over the whole distance.
