What does this tool do?
Swimmers usually compare sets by pace per 100 m or 100 yd rather than total time. Enter a distance and elapsed time to get that pace, plus the equivalent per-50 split and average speed.
The Formula
Pace per 100 = total seconds ÷ distance × 100Frequently Asked Questions
Why is swim pace measured per 100?
Per-100 pace is the standard comparison unit in swimming. It keeps sets of different lengths comparable and makes target times easy to calculate.
Does pool length change my pace?
Yes. A 25 m pool has twice as many turns and push-offs as a 50 m pool, which usually makes the same swimmer faster over the shorter course.
