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.
Millipascal
A millipascal (mPa) is a unit of pressure equal to one thousandth of a pascal, the SI unit of pressure.
History/Origin
The millipascal is derived from the pascal, which was named after Blaise Pascal. It is used in contexts requiring very small pressure measurements, but its usage is relatively uncommon due to the widespread adoption of the pascal.
Current Use
Millipascals are primarily used in scientific and engineering fields to measure very low pressures, such as in fluid dynamics, vacuum systems, and sensitive instrumentation within the 'Pressure' converter category of 'Common Converters'.
