Kilonewton/square Meter
A kilonewton per square meter (kN/m^2) is a unit of pressure equivalent to one kilonewton of force applied over an area of one square meter.
History/Origin
The kilonewton per square meter is derived from the SI units of force (newton) and area (square meter). It has been used in engineering and scientific contexts to measure pressure, especially in fields like civil and mechanical engineering, since the adoption of the SI system.
Current Use
Today, kN/m^2 is commonly used in engineering to specify stress, pressure, and load measurements, often interchangeably with the Pascal (Pa), where 1 kN/m^2 equals 1,000 Pa.
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in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
