Convert millimeter water (4°C) to picopascal
Please provide values below to convert millimeter water (4°C) [mmH2O] to picopascal [pPa], or Convert picopascal to millimeter water (4°C).
1 mmH2O = 9.8064e+12 pPa. To convert millimeter water (4°C) to picopascal, multiply the value by 9.8064e+12; to go the other way, divide by it (1 pPa = 1.0197e-13 mmH2O). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 mmH2O = 9.8064e+12 pPa
- 1 pPa = 1.0197e-13 mmH2O
- 10 mmH2O = 9.8064e+13 pPa
- 100 mmH2O = 9.8064e+14 pPa

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.
Picopascal
The picopascal (pPa) is a unit of pressure equal to 10^-12 pascals, representing an extremely small pressure measurement.
History/Origin
The picopascal was introduced as part of the SI prefixes to measure very low pressures, primarily in scientific research and specialized fields requiring high precision. Its usage has been limited due to the small magnitude of the unit.
Current Use
Currently, the picopascal is rarely used in practical applications but may be employed in scientific experiments involving ultra-low pressure measurements or in theoretical contexts where extremely small pressure values are relevant.
