Calculation method and formula
Distance swum ÷ Counted strokes
Understand the inputs
- Distance swum
- Minimum 0.01. Use a measured value or your own assumption.
- Distance unit
- Choose the matching option; it determines the table value or calculation variant.
- Counted strokes
- Minimum 1. Whole number.
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.
