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.
Microbar
A microbar (µbar) is a unit of pressure equal to one millionth of a bar, where 1 bar equals 100,000 pascals.
History/Origin
The microbar was introduced as a subunit of the bar to measure very low pressures, particularly in meteorology and vacuum technology, gaining usage in the 20th century as precision pressure measurements became more common.
Current Use
Today, the microbar is used primarily in meteorology for measuring atmospheric pressure variations and in scientific research requiring precise low-pressure measurements.
