Decipascal
The decipascal (dPa) is a unit of pressure equal to one-tenth of a pascal, where 1 dPa = 0.1 Pa.
History/Origin
The decipascal was introduced as a metric unit to provide finer measurement options within the pressure unit system, though it is rarely used in practice due to the widespread adoption of the pascal.
Current Use
The decipascal is seldom used in modern applications; pressure measurements typically utilize pascals or larger units such as kilopascals. It may appear in specialized scientific contexts or educational settings for illustrative purposes.
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.
