The instruments used to measure wind are known as anemometers and can record wind speed, direction and the strength of gusts. The normal unit of wind speed is the knot (nautical mile per hour = 0.51 m sec-1 = 1.15 mph).
What is wind speed and how is it measured?
The speed of that wind can be measured using a tool called an anemometer . An anemometer looks like a weather vane, but instead of measuring which direction the wind is blowing with pointers, it has four cups so that it can more accurately measure wind speed.
