Turn any swim into a clear pace per 100 metres or 100 yards plus an average speed. Enter the distance you covered, choose your unit, and add your time — pace per 100 is the standard way swimmers compare efforts across different set lengths and pool sizes.
How it works
Two figures are derived from your distance and time:
- Pace per 100 = (total seconds ÷ total distance) × 100, shown as minutes:seconds. This is simply how long 100 of your chosen unit takes at your average effort.
- Average speed = distance in metres ÷ time in seconds for m/s, then × 3.6 for km/h. When you use yards, the distance is first converted with 1 yard = 0.9144 m.
Example
A 1500 m swim in 25:00 (1500 seconds):
- Pace per 100 = (1500 ÷ 1500) × 100 = 100 s = 1:40 / 100 m
- Speed = 1500 ÷ 1500 = 1.0 m/s = 3.6 km/h
| Input | Value |
|---|---|
| Distance | 1500 m |
| Time | 25:00 |
| Pace | 1:40 / 100 m |
| Speed | 1.0 m/s (3.6 km/h) |
