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.
Pound-Force/square Foot
Pound-force per square foot (lbf/ft^2) is a unit of pressure representing the force of one pound-force applied over an area of one square foot.
History/Origin
This unit has been traditionally used in the United States for measuring pressure, especially in fields like construction and engineering, originating from the imperial system of units.
Current Use
Today, pound-force per square foot is primarily used in specific engineering and construction contexts within the US, although it has largely been replaced by SI units like Pascals in scientific and international applications.
