Please provide values below to convert millimeter water (4°C) [mmH2O] to kilogram-force/square meter [kgf/m^2], or Convert kilogram-force/square meter to millimeter water (4°C).
How to Convert Millimeter Water (4°c) to Kilogram-Force/square Meter
1 mmH2O = 0.99997246766225 kgf/m^2
Example: convert 15 mmH2O to kgf/m^2:
15 mmH2O = 15 × 0.99997246766225 kgf/m^2 = 14.9995870149337 kgf/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.
Kilogram-Force/square Meter
Kilogram-force per square meter (kgf/m^2) is a unit of pressure representing the force of one kilogram-force applied over an area of one square meter.
History/Origin
The unit originated from the use of kilogram-force, a gravitational force unit based on the kilogram, before the adoption of SI units. It was commonly used in engineering and physics to measure pressure in contexts where gravitational force was considered.
Current Use
Today, kgf/m^2 is largely obsolete and replaced by the SI unit Pascal (Pa). However, it may still be encountered in legacy systems or specific regional applications related to pressure measurement.
