Please provide values below to convert nanopascal [nPa] to millimeter water (4°C) [mmH2O], or Convert millimeter water (4°C) to nanopascal.
How to Convert Nanopascal to Millimeter Water (4°c)
1 nPa = 1.01974428892211e-10 mmH2O
Example: convert 15 nPa to mmH2O:
15 nPa = 15 × 1.01974428892211e-10 mmH2O = 1.52961643338316e-09 mmH2O

Nanopascal
The nanopascal (nPa) is a unit of pressure equal to one billionth of a pascal, where 1 nPa = 10^-9 Pa.
History/Origin
The nanopascal was introduced as part of the SI unit system's extension to accommodate very small pressure measurements, primarily in scientific research involving micro- and nanoscale phenomena.
Current Use
Nanopascals are used in high-precision scientific applications such as atmospheric pressure measurements, microfluidics, and nanotechnology research where extremely low pressure differences need to be quantified.
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.
