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.


Centimeter Mercury (0°c)

Centimeter mercury (0°C) is a unit of pressure measurement representing the pressure exerted by a one-centimeter column of mercury at 0°C.

History/Origin

The centimeter mercury was historically used in barometry and pressure measurements before the adoption of the pascal. It originated from the use of mercury columns in barometers to measure atmospheric pressure, with the unit reflecting the height of the mercury column.

Current Use

Today, the centimeter mercury is largely obsolete and replaced by SI units like the pascal. However, it is still used in some medical and historical contexts to measure blood pressure and atmospheric pressure in certain regions.
