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.
Standard Atmosphere
The standard atmosphere (atm) is a unit of pressure defined as 101,325 pascals, representing the average atmospheric pressure at sea level.
History/Origin
The standard atmosphere was established in the early 20th century to provide a consistent reference for pressure measurements, based on the average atmospheric pressure at sea level under standard conditions.
Current Use
The atm is commonly used in fields such as meteorology, aviation, and engineering to express pressure, especially in contexts involving gases and atmospheric conditions.
