Millimeters
A barometer measures pressure, and the SI unit for pressure is the Pascal, equivalent to Newtons / square meter.
The atmosphere pressure is commonly measured using a device called a barometer. This instrument detects the weight of the air above it, which decreases as altitude increases. The most common unit of measurement for atmosphere pressure is the bar or millibar.
A wind vane measures direction of the wind. Millibars are a measure of pressure. A barometer measures in millibars.
