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in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
Ton-Force (Short)/sq. Foot
Ton-force per square foot (tonf/ft²) is a unit of pressure representing the force exerted by one ton-force distributed over an area of one square foot.
History/Origin
The ton-force per square foot originated from the use of the ton-force as a unit of force in the Imperial system, primarily in engineering and construction contexts, to measure pressure or stress levels. Its usage has declined with the adoption of SI units but remains relevant in specific industries.
Current Use
Today, ton-force per square foot is rarely used in modern engineering, having been largely replaced by SI units such as pascals. It may still be encountered in legacy systems or specific regional applications related to structural and material stress assessments.
