Convert millimeter water (4°C) to kilonewton/square meter
Please provide values below to convert millimeter water (4°C) [mmH2O] to kilonewton/square meter [kN/m^2], or Convert kilonewton/square meter to millimeter water (4°C).
How to Convert Millimeter Water (4°c) to Kilonewton/square Meter
1 mmH2O = 0.00980638 kN/m^2
Example: convert 15 mmH2O to kN/m^2:
15 mmH2O = 15 × 0.00980638 kN/m^2 = 0.1470957 kN/m^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.
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.
