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.
Kilonewton/square Meter
A kilonewton per square meter (kN/m^2) is a unit of pressure equivalent to one kilonewton of force applied over an area of one square meter.
History/Origin
The kilonewton per square meter is derived from the SI units of force (newton) and area (square meter). It has been used in engineering and scientific contexts to measure pressure, especially in fields like civil and mechanical engineering, since the adoption of the SI system.
Current Use
Today, kN/m^2 is commonly used in engineering to specify stress, pressure, and load measurements, often interchangeably with the Pascal (Pa), where 1 kN/m^2 equals 1,000 Pa.
