Wind speed is measured using an anemometer. It is typically made up of cups attached to spindle. The stronger the wind the faster the cups rotate and the higher the reading. Several readings should be taken over a couple of minutes and an average taken. The measurement is sometimes made in knots but any speed unit is possible.
