Psi

Psi (pounds per square inch) is a unit of pressure measurement representing the force of one pound applied to an area of one square inch.

History/Origin

The psi originated in the United States as a customary unit of pressure, commonly used in engineering and industrial applications. It became standardized with the development of the imperial system of units.

Current Use

Psi is widely used today in various fields such as automotive tire pressure, plumbing, and industrial pressure measurements, especially in the United States and other countries using imperial units.


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.
