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.
Centipascal
The centipascal (cPa) is a unit of pressure equal to one hundredth of a pascal, where 1 pascal (Pa) is the SI unit of pressure defined as one newton per square meter.
History/Origin
The centipascal was introduced as a smaller unit of pressure for more precise measurements, particularly in scientific and engineering contexts, although it is not widely used in practice. It derives from the pascal, the SI base unit established in 1960.
Current Use
The centipascal is rarely used in modern applications; pressure measurements typically utilize pascals or larger units such as kilopascals. It may appear in specialized scientific literature or calibration contexts where fine pressure distinctions are necessary.
