Convert millimeter water (4°C) to decipascal
Please provide values below to convert millimeter water (4°C) [mmH2O] to decipascal [dPa], or Convert decipascal to millimeter water (4°C).
How to Convert Millimeter Water (4°c) to Decipascal
1 mmH2O = 98.0638 dPa
Example: convert 15 mmH2O to dPa:
15 mmH2O = 15 × 98.0638 dPa = 1470.957 dPa

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.
Decipascal
The decipascal (dPa) is a unit of pressure equal to one-tenth of a pascal, where 1 dPa = 0.1 Pa.
History/Origin
The decipascal was introduced as a metric unit to provide finer measurement options within the pressure unit system, though it is rarely used in practice due to the widespread adoption of the pascal.
Current Use
The decipascal is seldom used in modern applications; pressure measurements typically utilize pascals or larger units such as kilopascals. It may appear in specialized scientific contexts or educational settings for illustrative purposes.
