Convert millimeter water (4°C) to newton/square centimeter
Please provide values below to convert millimeter water (4°C) [mmH2O] to newton/square centimeter [N/cm^2], or Convert newton/square centimeter to millimeter water (4°C).
How to Convert Millimeter Water (4°c) to Newton/square Centimeter
1 mmH2O = 0.000980638 N/cm^2
Example: convert 15 mmH2O to N/cm^2:
15 mmH2O = 15 × 0.000980638 N/cm^2 = 0.01470957 N/cm^2

Millimeter Water (4°c)
Millimeter water (4°C) is a unit of pressure measuring the height of a water column at 4 degrees Celsius that exerts a specific pressure.
History/Origin
The unit originated from the use of water columns to measure pressure, particularly in hydrology and medical applications, with standardization based on the density of water at 4°C.
Current Use
It is primarily used in medical and scientific contexts to measure low pressures, such as intracranial pressure, respiratory pressures, and in calibration of pressure sensors.
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.
