Critical Swim Speed (CSS) Calculator

This calculator helps swimmers determine their Critical Swim Speed (CSS), a valuable metric for training and performance analysis. Ideal for competitive and recreational swimmers aiming to optimize their swim training routines.

CSS Calculator

Results

CSS Speed 0.00 m/s

Data Source and Methodology

All calculations are based on established swimming performance metrics. For further details, please refer to the authoritative source at example.com.

The Formula Explained

CSS = \(\frac{\text{Distance}}{\text{Time}}\)

Glossary of Variables

How It Works: A Step-by-Step Example

For a 400m swim completed in 5:20 (five minutes and twenty seconds), the CSS is calculated as:

CSS = 400 / 320 = 1.25 m/s
