Please provide values below to convert kilogram-force/sq. millimeter [kgf/mm^2] to millimeter water (4°C) [mmH2O], or Convert millimeter water (4°C) to kilogram-force/sq. millimeter.
How to Convert Kilogram-Force/sq. Millimeter to Millimeter Water (4°c)
1 kgf/mm^2 = 1000027.5330958 mmH2O
Example: convert 15 kgf/mm^2 to mmH2O:
15 kgf/mm^2 = 15 × 1000027.5330958 mmH2O = 15000412.996437 mmH2O

Kilogram-Force/sq. Millimeter
Kilogram-force per square millimeter (kgf/mm²) is a unit of pressure representing the force of one kilogram-force applied over an area of one square millimeter.
History/Origin
The unit originated from the use of kilogram-force, a gravitational force unit based on the kilogram, and was commonly used in engineering and material science to measure pressure before the adoption of SI units. Its usage has declined with the standardization of the pascal (Pa).
Current Use
Today, kgf/mm² is still used in some engineering fields, especially in material strength and pressure measurements, but it is largely replaced by SI units like the pascal (Pa) or megapascals (MPa).
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.
