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.
Kilopascal
The kilopascal (kPa) is a unit of pressure equal to 1,000 pascals, where one pascal is defined as one newton per square meter.
History/Origin
The kilopascal was introduced as part of the metric system to provide a convenient unit for measuring pressure, especially in scientific and engineering contexts, replacing larger units like the bar in many applications.
Current Use
The kilopascal is widely used today in various fields such as meteorology, engineering, and physics to measure pressure, including tire pressure, blood pressure, and atmospheric pressure.
