Convert Barye to Micropascal (Ba to μPa)

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

The micropascal (symbol: µPa) is an SI-derived unit of pressure equal to one millionth (10^-6) of a pascal. It is commonly used in acoustics, sound pressure measurements, atmospheric science, and precision laboratory applications involving extremely small pressure variations. The micropascal uses the SI prefix micro, representing a factor of one millionth.

One micropascal is equal to 0.000001 pascal, 0.001 millipascal, 1,000 nanopascals, 1×10^-11 bar, and 9.86923×10^-12 standard atmosphere. The micropascal is particularly important in acoustics, where it is used as the reference unit for sound pressure levels.
