Convert centimeter water (4°C) to newton/square centimeter
Please provide values below to convert centimeter water (4°C) [cmH2O] to newton/square centimeter [N/cm^2], or Convert newton/square centimeter to centimeter water (4°C).
How to Convert Centimeter Water (4°c) to Newton/square Centimeter
1 cmH2O = 0.00980638 N/cm^2
Example: convert 15 cmH2O to N/cm^2:
15 cmH2O = 15 × 0.00980638 N/cm^2 = 0.1470957 N/cm^2

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 Centimeter
The newton per square centimeter (N/cm²) is a unit of pressure representing the force of one newton applied over an area of one square centimeter.
History/Origin
The unit derives from the SI unit of force, the newton, combined with the centimeter as a unit of area. It has been used in fields like engineering and physics to measure pressure, especially in contexts where the centimeter is a convenient unit of length. Its usage predates the widespread adoption of the pascal (Pa), which is equivalent to N/m².
Current Use
The N/cm² is still used in certain engineering and industrial applications, particularly in contexts where pressure measurements are expressed in centimeters rather than meters. It is also used in some scientific fields for convenience, though the pascal is more common internationally.
