Convert centimeter water (4°C) to megapascal

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

1 cmH2O = 9.80638e-05 MPa. To convert centimeter water (4°C) to megapascal, multiply the value by 9.80638e-05; to go the other way, divide by it (1 MPa = 10197.4428892 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 = 9.80638e-05 MPa

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.


Megapascal

The megapascal (MPa) is a unit of pressure equal to one million pascals, where one pascal (Pa) is the pressure exerted by a force of one newton per square meter.

History/Origin

The megapascal was introduced as part of the International System of Units (SI) to provide a convenient scale for measuring high pressures, especially in engineering and scientific applications, replacing larger units like the bar in many contexts.

Current Use

The MPa is widely used today in engineering, material science, and industrial applications to specify pressures in fields such as hydraulics, pneumatics, and structural engineering.
