Convert centimeter water (4°C) to petapascal

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

1 cmH2O = 9.8064e-14 PPa. To convert centimeter water (4°C) to petapascal, multiply the value by 9.8064e-14; to go the other way, divide by it (1 PPa = 1.0197e+13 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-14 PPa
  • 1 PPa = 1.0197e+13 cmH2O
  • 10 cmH2O = 9.8064e-13 PPa
  • 100 cmH2O = 9.8064e-12 PPa

How to Convert Centimeter Water (4°c) to Petapascal

1 cmH2O = 9.80638e-14 PPa

Example: convert 15 cmH2O to PPa:
15 cmH2O = 15 × 9.80638e-14 PPa = 1.470957e-12 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.


Petapascal

A petapascal (PPa) is a unit of pressure equal to 10^15 pascals.

History/Origin

The petapascal was introduced as part of the SI prefix system to represent extremely high pressures, mainly in scientific and industrial contexts, as the need to measure such large values arose with advancements in high-pressure physics and astrophysics.

Current Use

Petapascal is used in fields such as astrophysics, geophysics, and high-pressure physics to quantify extremely high pressures, such as those found in planetary interiors or during high-energy experiments.
