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.
Kilopascal
The kilopascal (kPa) is a unit of pressure equal to 1,000 pascals, where one pascal is defined as one newton per square meter.
History/Origin
The kilopascal was introduced as part of the metric system to provide a convenient unit for measuring pressure, especially in scientific and engineering contexts, replacing larger units like the bar in many applications.
Current Use
The kilopascal is widely used today in various fields such as meteorology, engineering, and physics to measure pressure, including tire pressure, blood pressure, and atmospheric pressure.
