Bar (bar) to Millibar (mbar) Conversion
Bar
The bar is a unit of pressure equal to exactly 100,000 pascals (100 kPa), accepted for use with the SI by the BIPM. It is close to one standard atmosphere (1 atm = 1.01325 bar) making it convenient for many practical applications. The bar is widely used in meteorology (weather maps), industrial gas and fluid systems, and tyre inflation in continental Europe. A typical car tyre is inflated to 2.2–2.5 bar; scuba diving tanks are filled to 200–300 bar.
Millibar
The millibar (mbar) is a unit of pressure equal to one thousandth of a bar (100 Pa). It is the standard unit for atmospheric pressure in meteorology: standard atmospheric pressure is 1,013.25 mbar, and weather maps plot isobars (lines of equal pressure) in millibars or hectopascals (1 hPa = 1 mbar). The eye of a powerful hurricane can have a central pressure below 900 mbar, while high-pressure systems typically exceed 1,020 mbar.
