About These Units
Bar (bar)
A bar equals 100,000 Pascals or approximately 14.5 PSI. Bar is slightly less than standard atmospheric pressure (1.01325 bar). Bars measure tire pressure, compressed gas cylinders, scuba tank pressure (200-300 bar), and industrial processes.
Millibar (mbar)
A millibar (mbar) equals 100 Pascals or one hectopascal. Millibars are used in meteorology for atmospheric pressure and weather forecasting. Standard sea level pressure is 1013.25 mbar. Hurricanes have central pressures below 950 mbar.
