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.
Centimeter Mercury (0°c)
Centimeter mercury (0°C) is a unit of pressure measurement representing the pressure exerted by a one-centimeter column of mercury at 0°C.
History/Origin
The centimeter mercury was historically used in barometry and pressure measurements before the adoption of the pascal. It originated from the use of mercury columns in barometers to measure atmospheric pressure, with the unit reflecting the height of the mercury column.
Current Use
Today, the centimeter mercury is largely obsolete and replaced by SI units like the pascal. However, it is still used in some medical and historical contexts to measure blood pressure and atmospheric pressure in certain regions.
