Kilogram-Force/sq. Millimeter
Kilogram-force per square millimeter (kgf/mm²) is a unit of pressure representing the force of one kilogram-force applied over an area of one square millimeter.
History/Origin
The unit originated from the use of kilogram-force, a gravitational force unit based on the kilogram, and was commonly used in engineering and material science to measure pressure before the adoption of SI units. Its usage has declined with the standardization of the pascal (Pa).
Current Use
Today, kgf/mm² is still used in some engineering fields, especially in material strength and pressure measurements, but it is largely replaced by SI units like the pascal (Pa) or megapascals (MPa).
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in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
