Please provide values below to convert millimeter water (4°C) [mmH2O] to centipascal [cPa], or Convert centipascal to millimeter water (4°C).
How to Convert Millimeter Water (4°c) to Centipascal
1 mmH2O = 980.638 cPa
Example: convert 15 mmH2O to cPa:
15 mmH2O = 15 × 980.638 cPa = 14709.57 cPa

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.
Centipascal
The centipascal (cPa) is a unit of pressure equal to one hundredth of a pascal, where 1 pascal (Pa) is the SI unit of pressure defined as one newton per square meter.
History/Origin
The centipascal was introduced as a smaller unit of pressure for more precise measurements, particularly in scientific and engineering contexts, although it is not widely used in practice. It derives from the pascal, the SI base unit established in 1960.
Current Use
The centipascal is rarely used in modern applications; pressure measurements typically utilize pascals or larger units such as kilopascals. It may appear in specialized scientific literature or calibration contexts where fine pressure distinctions are necessary.
