Torr
The torr is a unit of pressure defined as 1 millimeter of mercury (mmHg) at standard gravity and temperature, approximately equal to 133.322 pascals.
History/Origin
The torr was introduced by Evangelista Torricelli in 1644, based on his experiments with mercury barometers, as a unit to measure atmospheric pressure. It was historically used in meteorology and physics before the adoption of the pascal.
Current Use
Today, the torr is primarily used in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
Pound-Force/square Foot
Pound-force per square foot (lbf/ft^2) is a unit of pressure representing the force of one pound-force applied over an area of one square foot.
History/Origin
This unit has been traditionally used in the United States for measuring pressure, especially in fields like construction and engineering, originating from the imperial system of units.
Current Use
Today, pound-force per square foot is primarily used in specific engineering and construction contexts within the US, although it has largely been replaced by SI units like Pascals in scientific and international applications.
