Convert centimeter water (4°C) to picopascal

Please provide values below to convert centimeter water (4°C) [cmH2O] to picopascal [pPa], or Convert picopascal to centimeter water (4°C).

1 cmH2O = 9.8064e+13 pPa. To convert centimeter water (4°C) to picopascal, multiply the value by 9.8064e+13; to go the other way, divide by it (1 pPa = 1.0197e-14 cmH2O). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Quick Reference

  • 1 cmH2O = 9.8064e+13 pPa
  • 1 pPa = 1.0197e-14 cmH2O
  • 10 cmH2O = 9.8064e+14 pPa
  • 100 cmH2O = 9.8064e+15 pPa

Centimeter Water (4°c)

Centimeter water (4°C), symbol cmH2O, is a unit of pressure representing the pressure exerted by a one-centimeter column of water at 4 degrees Celsius.

History/Origin

The centimeter water was developed as a practical unit of pressure measurement in medical and engineering contexts, especially for low-pressure measurements such as respiratory and fluid pressure, originating from the use of water columns in manometers.

Current Use

It is primarily used in medical settings to measure intracranial pressure, respiratory pressures, and other low-pressure applications where precise measurement of small pressure differences is required.


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.
