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.
Dyne/square Centimeter
A dyne per square centimeter (dyn/cm^2) is a unit of pressure representing the force of one dyne applied over an area of one square centimeter.
History/Origin
The dyne is a unit of force in the centimeter-gram-second (CGS) system, introduced in the 19th century. The dyn/cm^2 has been used primarily in physics and engineering to measure pressure in CGS units before the widespread adoption of the SI system.
Current Use
Today, the dyn/cm^2 is rarely used outside specialized scientific contexts; pressure is more commonly expressed in pascals (Pa) in the SI system. However, it remains relevant in certain fields like astrophysics and plasma physics where CGS units are still employed.
