An anemometer is commonly used to measure wind speed. In meteorology, wind speed, or wind flow speed, is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in temperature. Wind speed is now commonly measured with an anemometer What Measures Wind Speed? Wind is measured by using the instrument called anemometer. The unit of anemometer is FPM or feet per minute. An Anemometer has has five basic types A conventional three-cup anemometer only measures wind speed, but there are two main ways to measure wind direction as well: One of the cups can have an attached tag to alter the wind force on it, making the anemometer speed up and slow down once per cycle, creating a cyclic pulsation For meteorological purposes, wind speeds are generally measured in terms of knots (nautical miles per hour) or meters per second, depending on locale. In METAR* data, KT is used to indicate knots and MPS to indicate meters per second. Likewise, what is the anemometer measured in? The anemometer measures in feet per minute, or FPM
