millibar

millibar
A unit of measurement of pressure. In the standard atmosphere, air exerts a pressure of one bar at sea level. A bar is equal to 106 dynes per square centimeter. One bar = 1000 millibars = 750.8 mm Hg = 29.53 in Hg. The average sea level pressure is 1013.2 millibars or 29.92 in of mercury. Altimeter settings used to be given in millibars but now are more likely to be given in hPa (hectopascals). The values of millibars and hectopascals are the same.
