Detailed explanation-1: -One tool they use for measuring wind direction is a wind vane. It spins and points in the direction from which the wind is blowing. The wind can blow in every direction, but in many places most winds will blow in the same general direction.

Detailed explanation-2: -A wind/weather vane is used to determine wind direction. The wind vane should be placed in an open area where it can rotate freely as the wind direction changes. An anemometer is used to measure wind speed.

Detailed explanation-3: -A wind vane is mounted on a shaft or spire that is elevated off the ground. The wind catches the rudder blade and makes it rotate. The narrow end of the vane points into the wind and tells you the direction the wind is coming from. Modern wind vanes are technical and highly sensitive instruments.

Detailed explanation-4: -Wind direction results from the orientation of those air pressure differences, with air moving from higher to lower air pressure. In reality, wind blows from higher to lower air pressure at an average value of about 30 degrees across the lines of equal air pressure, inward toward the lower air pressure.

Detailed explanation-5: -Answer and Explanation: A wind vane doesn’t use units of measurement. It doesn’t really measure anything. It indicates the direction of the wind.
