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.
Exapascal
An exapascal (EPa) is a unit of pressure equal to 10^18 pascals, used to measure extremely high pressures.
History/Origin
The exapascal was introduced as part of the International System of Units (SI) prefixes to represent very large pressure values, primarily in scientific and engineering contexts involving high-pressure phenomena.
Current Use
The exapascal is mainly used in fields such as geophysics, astrophysics, and high-pressure physics to describe immense pressures found in planetary interiors, stellar environments, and experimental high-pressure research.
