Units
We use knots and degrees Celsius as our default units. These units are often used by sailors, kiters, surfers, windsurfers and paragliders. Use website settings to switch between units and 7 different languages at any time. For converting between wind speed units such as knots, km/h (kilometers per hour), m/s (meters per second), and mph (miles per hour) use our wind speed calculator.
