pound per square inch
Definition: Pound per square inch (symbol: psi or lbf/in²) is a unit of pressure in the imperial and US customary systems. It is defined as the pressure resulting from a force of one pound-force applied to an area of one square inch.
History/origin: The pound per square inch is rooted in the English system of units. Its widespread use grew with the development of steam engines and other technologies requiring pressure measurements.
Current use: psi is commonly used in the United States for measuring tire pressure, hydraulic pressure, steam pressure, and the pressure of compressed gases. It's prevalent in automotive, manufacturing, and various engineering applications.
bar
Definition: The bar (symbol: bar) is a metric unit of pressure, but not part of the International System of Units (SI). It is defined as exactly equal to 100,000 Pa (100 kPa), which is slightly less than current average atmospheric pressure on Earth at sea level.
History/origin: The bar was introduced by British meteorologist William Napier Shaw in 1909.
Current use: The bar is used in various fields, including meteorology, diving (for measuring pressure underwater), and industrial applications. It is often used when a unit close to atmospheric pressure is convenient.
