Convert hectopascal to millimeter water (4°C)
Please provide values below to convert hectopascal [hPa] to millimeter water (4°C) [mmH2O], or Convert millimeter water (4°C) to hectopascal.
1 hPa = 10.1974428892 mmH2O. To convert hectopascal to millimeter water (4°C), multiply the value by 10.1974428892; to go the other way, divide by it (1 mmH2O = 0.0980638 hPa). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Hectopascal
The hectopascal (hPa) is a unit of pressure equal to 100 pascals, commonly used in meteorology to measure atmospheric pressure.
History/Origin
The hectopascal was introduced as part of the metric system and became widely adopted in meteorology during the 20th century for standardizing atmospheric pressure measurements.
Current Use
Today, the hectopascal is predominantly used in weather reporting and forecasting to indicate atmospheric pressure, with standard sea-level pressure approximately 1013 hPa.
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.
