How Do You Measure Wind Speed?

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.

How do you calculate wind speed?

Calculate a miles per hour wind speed in

feet per hour, then divide by the number of feet in a knot

. For the example wind speed of 100 mph, do as follows: 100 mph x 5,280 feet = 528,000 feet per hour; 528,000 feet per hour/6,080 feet = 86.8 knots.

What is used to measure wind speed?

An anemometer

is an instrument that measures wind speed and wind pressure. Anemometers are important tools for meteorologists, who study weather patterns. They are also important to the work of physicists, who study the way air moves.

How do you measure wind speed without an anemometer?
