Convert Exapascal to Barye (EPa to Ba)

Exapascal (EPa) and Barye (Ba) are both units of pressure. With the conversion form below, you can effortlessly and accurately convert exapascal to barye. This free online calculator tool makes it simple and easy to perform the conversion from EPa 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 exapascal (symbol: EPa) is an SI-derived unit of pressure equal to one quintillion (10¹⁸) pascals. It is an extremely large pressure unit used primarily in theoretical physics, geophysics, astrophysics, and advanced scientific research involving exceptionally high pressures. The exapascal uses the SI prefix exa, representing a factor of 10¹⁸.

One exapascal is equal to 1,000 petapascals, 1,000,000 terapascals, 1,000,000,000 gigapascals, 10,000,000,000,000 bar, and 1×10¹⁸ pascals. Although rarely encountered outside research, the exapascal is part of the complete SI pressure scale.

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.
