Gigapascal
A gigapascal (GPa) is a unit of pressure equal to one billion pascals, where one pascal (Pa) is the force of one newton per square meter.
History/Origin
The gigapascal was introduced as part of the International System of Units (SI) to measure high-pressure phenomena, especially in materials science and geophysics, as a larger unit than the pascal for convenience.
Current Use
GPa is commonly used to quantify stress, pressure in geological formations, material strength, and high-pressure physics applications.
Pascal
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter.
History/Origin
Named after Blaise Pascal, the pascal was adopted as the SI unit of pressure in 1971, replacing earlier units like the bar and atmosphere.
Current Use
The pascal is widely used in science, engineering, and meteorology to measure pressure, with common applications including atmospheric pressure, tire pressure, and fluid pressure in systems.
