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.
Millibar
A millibar (mbar) is a unit of pressure measurement equal to one-thousandth of a bar, commonly used in meteorology to measure atmospheric pressure.
History/Origin
The millibar was introduced in the early 20th century as a convenient unit for meteorological measurements, replacing the bar in many applications due to its smaller size. It became widely adopted in weather reporting and atmospheric studies.
Current Use
Today, the millibar is still used in meteorology and atmospheric sciences to report atmospheric pressure, although it is gradually being replaced by the Pascal (Pa) in scientific contexts. It remains a standard unit in weather forecasts and reports.
