Convert Gigapascal to Millipascal (GPa to Millipascal)

Gigapascal (GPa) and Millipascal (Millipascal) are both units of pressure. With the conversion form below, you can effortlessly and accurately convert gigapascal to millipascal. This free online calculator tool makes it simple and easy to perform the conversion from GPa unit to the Millipascal 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 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.

The millipascal (symbol: mPa) is an SI-derived unit of pressure equal to one-thousandth (0.001) of a pascal. It is used in acoustics, precision engineering, laboratory testing, and scientific research where very small pressure values need to be measured accurately. The millipascal uses the SI prefix milli, representing one-thousandth.

One millipascal is equal to 0.001 pascal, 1,000 micropascals, 0.1 centipascal, 1×10^-8 bar, and 9.86923×10^-9 standard atmosphere. The millipascal provides a convenient SI unit for expressing very low pressure values.
