Femtopascal
The femtopascal (fPa) is a unit of pressure equal to 10^-15 pascals.
History/Origin
The femtopascal is a derived SI unit introduced as part of the International System of Units' effort to create a comprehensive set of prefixes for very small measurements, although it is rarely used in practice.
Current Use
The femtopascal is primarily used in scientific research involving extremely low pressure measurements, such as in nanotechnology and quantum physics, but it remains a theoretical unit with limited practical application.
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.
