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.


Inch Mercury (32°f)

Inch of mercury at 32°F (inHg) is a unit of pressure measurement representing the height of a mercury column in inches, used primarily in meteorology and aviation.

History/Origin

The inch of mercury originated from barometric pressure measurements using a mercury barometer, with its use dating back to the 18th century. It became a standard unit in weather reporting and altitude measurement.

Current Use

Today, inHg is primarily used in meteorology to report atmospheric pressure, especially in the United States, and in aviation for altitude and pressure readings.
