What is Bar?

The bar is a unit of pressure equal to 100,000 pascals, which is very close to standard atmospheric pressure (101,325 Pa). This convenient relationship makes it widely used in industry. Scuba tank pressure is typically around 200 bar, espresso machines extract at about 9 bar, and fire extinguishers are pressurized to several bar. While not an SI unit, the bar is accepted for use with the SI in many countries.

What is Hectopascal?

The hectopascal equals 100 pascals and is the standard unit for atmospheric pressure in meteorology worldwide. Standard atmospheric pressure is 1013.25 hPa, and weather reports use hectopascals when describing high and low pressure systems and typhoon central pressures (such as 950 hPa). One hectopascal is exactly equal to one millibar. The international meteorological community switched from millibars to hectopascals in 1992.
