Unit Definitions
Psi
PSI (pounds per square inch) is a unit of pressure in the imperial and US customary systems. It represents the pressure resulting from a force of one pound-force applied to an area of one square inch.
Bar
Bar is a metric unit of pressure equal to 100,000 pascals (Pa), which is approximately equal to the atmospheric pressure on Earth at sea level. It is widely used in many technical applications, particularly in Europe.
Historical Context
PSI has been used since the development of steam engines in the 18th century. The bar was introduced in 1909 by the Norwegian meteorologist Vilhelm Bjerknes, and its name comes from the Greek word 'baros' meaning weight.
