Wind speed is a measurement of the speed of movement of the air, and is typically reported in miles per hour (mph) or kilometers per hour (kph). Reports for maritime and aeronautical operations may use those or knots (nautical miles per hour).
The Beaufort Wind Force Scale is a way to measure and describe the wind speed at sea. His scale had thirteen points e.g. calm = (0); storm = (13). In 1838 the British Navy made Beaufortâs Wind Force Scale the standard way to measure wind at sea. His Wind Force Scale was altered when steam ships became more popular than sailing ships.
