Please provide values below to convert centimeter water (4°C) [cmH2O] to kilogram-force/sq. millimeter [kgf/mm^2], or Convert kilogram-force/sq. millimeter to centimeter water (4°C).
How to Convert Centimeter Water (4°c) to Kilogram-Force/sq. Millimeter
1 cmH2O = 9.9997246766225e-06 kgf/mm^2
Example: convert 15 cmH2O to kgf/mm^2:
15 cmH2O = 15 × 9.9997246766225e-06 kgf/mm^2 = 0.000149995870149337 kgf/mm^2

Centimeter Water (4°c)
Centimeter water (4°C), symbol cmH2O, is a unit of pressure representing the pressure exerted by a one-centimeter column of water at 4 degrees Celsius.
History/Origin
The centimeter water was developed as a practical unit of pressure measurement in medical and engineering contexts, especially for low-pressure measurements such as respiratory and fluid pressure, originating from the use of water columns in manometers.
Current Use
It is primarily used in medical settings to measure intracranial pressure, respiratory pressures, and other low-pressure applications where precise measurement of small pressure differences is required.
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).
