Formulas Used

Pace per 100m

pace_100m = time_minutes / (distance_meters / 100)

Pace per 25m Lap

pace_lap = time_seconds / (distance_meters / 25)

Total Laps (25m)

total_laps = distance_meters / 25

How It Works

Swimming Pace Formula

Pace per 100m = Total Time / (Distance / 100)

Pace per lap (25m) = Total Seconds / (Distance / 25)

Swimming pace is typically measured per 100 meters in competitive swimming.

Worked Example

1500 meters in 30 minutes.

time_minutes = 30distance_meters = 1500
  1. 01Pace per 100m = 30 / (1500 / 100) = 30 / 15 = 2.00 min/100m
  2. 02Total laps = 1500 / 25 = 60 laps
  3. 03Pace per lap = 1800 sec / 60 = 30 sec/lap
