Convert pascal to millimeter water (4°C)
Please provide values below to convert pascal [Pa] to millimeter water (4°C) [mmH2O], or Convert millimeter water (4°C) to pascal.
1 Pa = 0.101974428892 mmH2O. To convert pascal to millimeter water (4°C), multiply the value by 0.101974428892; to go the other way, divide by it (1 mmH2O = 9.80638 Pa). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Pascal
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter.
History/Origin
Named after Blaise Pascal, the pascal was adopted as the SI unit of pressure in 1971, replacing earlier units like the bar and atmosphere.
Current Use
The pascal is widely used in science, engineering, and meteorology to measure pressure, with common applications including atmospheric pressure, tire pressure, and fluid pressure in systems.
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.
