Convert millimeter water (4°C) to kilogram-force/sq. millimeter
Please provide values below to convert millimeter water (4°C) [mmH2O] to kilogram-force/sq. millimeter [kgf/mm^2], or Convert kilogram-force/sq. millimeter to millimeter water (4°C).
How to Convert Millimeter Water (4°c) to Kilogram-Force/sq. Millimeter
1 mmH2O = 9.9997246766225e-07 kgf/mm^2
Example: convert 15 mmH2O to kgf/mm^2:
15 mmH2O = 15 × 9.9997246766225e-07 kgf/mm^2 = 1.49995870149337e-05 kgf/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.
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).
