Convert Barye to Gigapascal (Ba to GPa)

Barye (Ba) and Gigapascal (GPa) are both units of pressure. With the conversion form below, you can effortlessly and accurately convert barye to gigapascal. This free online calculator tool makes it simple and easy to perform the conversion from Ba unit to the GPa 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 gigapascal (symbol: GPa) is an SI-derived unit of pressure equal to one billion (10⁹) pascals. It is widely used in material science, structural engineering, mechanical engineering, and geology to express very high pressures and the elastic modulus of materials. The gigapascal uses the SI prefix giga, representing a factor of one billion.

One gigapascal is equal to 1,000,000,000 pascals, 1,000 megapascals, 1,000,000 kilopascals, 10,000 bars, and 145,037.738 pounds per square inch. The gigapascal is the standard unit for reporting the strength and stiffness of engineering materials.
