Swim Pace Calculator

Swim pace is measured per 100 metres (or yards) and is the standard unit for pool training and racing. A 2:00/100m pace means swimming 100 metres every 2 minutes

The calculator uses the standard published formula for swim pace. Results are accurate to the precision of the inputs you provide. For financial, medical, or legal decisions, always verify with a qualified professional.

This calculator works with inches. You can enter values in the units shown — the calculator handles all conversions internally.

The core formula is: Pace (sec/100m) = Total seconds / (Distance / 100). Each step in the calculation is shown so you can verify the result manually.
