Which units are commonly used to measure wind speed?

Wind speed is commonly measured in knots and miles per hour. Knots are often used in maritime and aviation contexts, as they represent nautical miles per hour, making them particularly relevant for navigation over water and in flight. Miles per hour is a standard unit of speed in various regions, particularly in the United States, making it widely recognized and used in everyday weather reports and travel contexts.

The other units listed do not serve as standard measurements for wind speed. For instance, feet per second and kilometers per hour are more commonly associated with general speed measurements rather than specifically for wind. Liters per minute pertains to volumetric flow rates, which do not apply to wind speed, while measuring wind in terms of the speed of sound is unconventional and not practical for meteorological purposes. Therefore, knowing that knots and miles per hour are the standard units helps reinforce the relevance and application of these measurements in weather reporting and aviation.
