Convert Millibar to Barye (mbar to Ba)

Millibar (mbar) and Barye (Ba) are both units of pressure. With the conversion form below, you can effortlessly and accurately convert millibar to barye. This free online calculator tool makes it simple and easy to perform the conversion from mbar unit to the Ba unit.

Pressure is the force applied perpendicular to a surface per unit area: P = F / A. The SI unit is the pascal (Pa), equal to one newton per square metre (1 Pa = 1 N/m²). Practical applications use larger units: the bar (1 bar = 100,000 Pa, close to standard atmospheric pressure), atmosphere (atm) (1 atm = 101,325 Pa), and psi (pounds per square inch, used in the US for tire and gas pressures). Blood pressure is measured in mmHg (millimetres of mercury), also called torr.

The millibar (symbol: mbar) is a non-SI unit of pressure equal to one-thousandth of a bar or exactly 100 pascals. It has been widely used in meteorology to report atmospheric pressure and remains common in weather forecasts, although the SI unit hectopascal has largely replaced it. One millibar is numerically equal to one hectopascal. More information is available in the bar (unit) reference.

One millibar is equal to 100 pascals, 1 hectopascal, 0.1 kilopascal, 0.001 bar, and 0.000986923 standard atmosphere. The millibar remains a familiar unit for atmospheric pressure worldwide.

The barye (symbol: Ba) is a CGS unit of pressure equal to one dyne per square centimeter or exactly 0.1 pascal. It was widely used in the centimetre-gram-second (CGS) system before the widespread adoption of SI units. Today, the barye is mainly encountered in historical scientific literature and older engineering references. It is part of the CGS system of units.

One barye is equal to 0.1 pascal, 1 dyne per square centimeter, 0.000001 bar, 0.0001 kilopascal, and 9.86923×10^-7 standard atmosphere. Although obsolete in most applications, the barye remains an important historical pressure unit.
