Convert gigapascal to pascal
Gigapascal
The gigapascal (GPa) is a unit of pressure equal to one billion pascals, or 1,000 megapascals. It is used in high-pressure physics and materials science to characterize the elastic moduli of very stiff materials such as diamond and metals. Diamond, for example, has a bulk modulus of approximately 442 GPa.
Pascal
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square metre (N/m²). It was adopted by the General Conference on Weights and Measures in 1971 and named after the French mathematician and physicist Blaise Pascal. Standard atmospheric pressure is approximately 101,325 Pa, and it is widely used in science, engineering, and meteorology.
