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.
Kilogram-Force/square Meter
Kilogram-force per square meter (kgf/m^2) is a unit of pressure representing the force of one kilogram-force applied over an area of one square meter.
History/Origin
The unit originated from the use of kilogram-force, a gravitational force unit based on the kilogram, before the adoption of SI units. It was commonly used in engineering and physics to measure pressure in contexts where gravitational force was considered.
Current Use
Today, kgf/m^2 is largely obsolete and replaced by the SI unit Pascal (Pa). However, it may still be encountered in legacy systems or specific regional applications related to pressure measurement.
