Calculation method and formula
Counted strokes ÷ Measurement time [Sek.] × 60
Understand the inputs
- Counted strokes
- Minimum 1. Whole number.
- Measurement time
- Unit: Sek.. Minimum 0.1. Use a measured value or your own assumption.
Assumptions and limitations
Compare only with equal pool length, stroke and counting method. Individual arm strokes differ from full cycles. Lower SWOLF alone does not prove better technique.
The formula uses the specified units. Displayed numbers are rounded; whole packs, item counts and full time periods may also be rounded within the calculation.
