Newton/square Centimeter
The newton per square centimeter (N/cm²) is a unit of pressure representing the force of one newton applied over an area of one square centimeter.
History/Origin
The unit derives from the SI unit of force, the newton, combined with the centimeter as a unit of area. It has been used in fields like engineering and physics to measure pressure, especially in contexts where the centimeter is a convenient unit of length. Its usage predates the widespread adoption of the pascal (Pa), which is equivalent to N/m².
Current Use
The N/cm² is still used in certain engineering and industrial applications, particularly in contexts where pressure measurements are expressed in centimeters rather than meters. It is also used in some scientific fields for convenience, though the pascal is more common internationally.
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in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
