Bar

Definition

A bar is a metric unit of pressure equal to 100,000 pascals (100 kPa). It is approximately equal to atmospheric pressure at sea level.

History

The bar was introduced in 1909 by the British meteorologist Napier Shaw. Its name derives from the Greek word 'baros' meaning weight. Though not an SI unit, it is widely accepted for use with SI.

Current use

Bars are extensively used in meteorology, oceanography, scuba diving (dive depth gauges), industrial applications, and tire pressure specifications in many European countries.

Pounds per Square Inch (psi)

Definition

Pounds per square inch (psi) is an imperial unit of pressure equal to the force of one pound-force applied to an area of one square inch. It equals approximately 6,894.76 pascals.

History

PSI evolved from the British imperial system and became the dominant pressure unit in American and British engineering. It gained widespread use with the industrialization of pneumatic and hydraulic systems.

Current use

PSI is the primary pressure unit in the United States for tire pressure, water pressure, hydraulic systems, compressed gas cylinders, and HVAC systems. It is also widely used in oil and gas industries.
