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.


Bar

The bar is a unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level.

History/Origin

The bar was introduced in 1909 by the British engineering community as a convenient unit for measuring pressure, especially in meteorology and engineering contexts.

Current Use

The bar is widely used in meteorology, engineering, and industrial applications to measure pressure, although the pascal is the SI base unit. It is also common in tire pressure measurements and other pressure-related fields.
