Centimeter Water (4°c)
Centimeter water (4°C), symbol cmH2O, is a unit of pressure representing the pressure exerted by a one-centimeter column of water at 4 degrees Celsius.
History/Origin
The centimeter water was developed as a practical unit of pressure measurement in medical and engineering contexts, especially for low-pressure measurements such as respiratory and fluid pressure, originating from the use of water columns in manometers.
Current Use
It is primarily used in medical settings to measure intracranial pressure, respiratory pressures, and other low-pressure applications where precise measurement of small pressure differences is required.
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.
