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.

torr

Definition: The torr (symbol: Torr) is a unit of pressure defined as 1/760 of a standard atmosphere. It is named after Evangelista Torricelli, an Italian physicist and mathematician.

History/origin: The torr is based on the pressure exerted by a column of mercury 1 millimeter high. It was originally defined in relation to the height of a mercury barometer.

Current use: The torr is used in vacuum technology, pressure measurement of low-pressure systems, and some areas of scientific research.
