millibar

millibar
(mb)
   a common metric unit of atmospheric pressure, equal to 0.001 bar, 100 pascals, 1000 dynes/cm2, about 0.0295 inches (0.7501 millimeters) of mercury, or about 0.014 504 lb/in2. A millibar is the same thing as a hectopascal (hPa), and some weather agencies have replaced the millibar with the hectopascal in an effort to conform with the SI. However, many meteorologists resist this change and continue to use millibars. In fact, an appropriate SI unit for atmospheric pressure would be the kilopascal (10 millibars or 0.145 038 lb/in2).
