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.
Newton/square Meter
The newton per square meter (N/m²) is the SI derived unit of pressure, representing the force of one newton applied over an area of one square meter.
History/Origin
The unit was established as part of the International System of Units (SI) in 1960, replacing earlier units like the pascal, which is now the standard SI unit for pressure.
Current Use
N/m², or pascals (Pa), is widely used in science, engineering, and meteorology to measure pressure, stress, and related quantities.
