Convert millimeter water (4°C) to newton/square millimeter
Please provide values below to convert millimeter water (4°C) [mmH2O] to newton/square millimeter [N/mm^2], or Convert newton/square millimeter to millimeter water (4°C).
How to Convert Millimeter Water (4°c) to Newton/square Millimeter
1 mmH2O = 9.80638e-06 N/mm^2
Example: convert 15 mmH2O to N/mm^2:
15 mmH2O = 15 × 9.80638e-06 N/mm^2 = 0.0001470957 N/mm^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 Millimeter
Newton per square millimeter (N/mm²) is a unit of pressure or stress, representing the force of one newton applied over an area of one square millimeter.
History/Origin
The unit derives from the SI base unit newton for force and the millimeter for area, commonly used in engineering and material science to measure stress and pressure. It has been in use since the adoption of the SI system, with increased application in fields requiring precise measurement of high pressures.
Current Use
N/mm² is widely used in engineering, material science, and construction to specify material strength, stress, and pressure levels, especially in contexts where high precision is required, such as in the specification of tensile strength and pressure ratings.
