Calculate swimming pace per 100 m (or 100 yd) and speed from a pool or open-water time.
| Input | Result |
|---|---|
| 1500 m in 35 min | 2:20 /100m · 0.71 m/s |
| 1000 m in 20 min | 2:00 /100m |
| 500 m in 12 min | 2:24 /100m |
Fitness lap swimmers typically hold 2:00–2:30 per 100 m; competitive age-group swimmers 1:15–1:45; elite 1500 m swimmers under 1:10.
Pace per 100 yd = pace per 100 m × 0.9144. A 2:20 /100m pace equals about 2:08 per 100 yd.
Pool swimming is measured in lengths and 100 m repeats; a per-100 pace maps directly onto interval training sets.
