health.swimming-SWOLF-efficiency Calculator
Calculates SWOLF score (swim stroke count + time per 25m/50m) as a composite efficiency metric for open water and pool swimmers. Lower SWOLF is better — elite distance swimmers achieve SWOLF scores below 35 for 25m; recreational swimmers are typically 45–60.
Inputs
Stroke Count 25M
Reference formula or conversion factor shown for context.
Time 25M S
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Pool Length M
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Results
SWOLF score
A numerical rating from the scoring model in use.
pace (min/100m)
Sample size or count used in the calculation.
swim velocity (m/s)
Reference formula or conversion factor shown for context.
SWOLF = stroke count + time (per length)
The computed linear length.
classification
Category assigned based on where the computed value falls on a defined scale. Check which standard or guideline defines these boundaries.
